Lids can support a spool on a holder or stored in a 21 quart cup container. This should be a thing.

Is this possible? I am running out of space in my box. Thanks.

The fan mount in the main body front intake partially obscures the M3/#6 screw hole underneath it for mounting the base. This is not a critical bug, and will be fixed in 0.9.9.

For now, inserting the screw at an angle or leaving it out resolves the issue. 0.9.8 remains on schedule with this bug.

It’s a safety thing. A switch will work on the hot or the neutral, but if you switch the neutral, the light fixture is still electrically live even with the switch turned off.

You really don’t want that. In the event of a ground fault or other problem at the light socket, you want to be able to kill power to it from the switch.

Quoted from somewhere else.

• Remove references to black wire in BOM
• Remove references to switching on neutral in assembly

Both the recently released SKR 3 and SKR 3 EZ boards have different screw positions than the other SKR 1.3+ boards.

• In the case of the SKR 3, there's only a 0.2mm difference, since they seem to have added a bit of padding.
• In the case of the SKR 3 EZ, however, it's trickier and would require a new layout since the board shifts the top-right screw hole to accommodate one of its EZ sockets.

The BTT SKR 3 Repo contains the sizing PDF as well as step files to make easier modifications and design new parts for the boards.

Affected Components

• MCU Tray
• Documentation

From this discussion:

Zip tie ports, great idea but that first one next to the power terminal has a really sharp bend at the spade connection that I am not a fan of. Perhaps move the rear circular cutout for the zipties 40mm to the front of the omnibox? Nitpicky but I probably wont use that ziptie port so the change is negligible.

Planning to get this cleaned up before 0.9.9 when the base gets universal PSU support.

Committed, just need confirmation of fit test. This is a placeholder, really.

Opening this as an issue so I will not forget again.

Documentation needs to be amended as follows:

/docs/bom.md

[-]M4 x 8mm, 14ea
[+]M4 x 8mm, 10ea
[+]M4 x 6mm, 4ea

/docs/assembly.md / 2. Main Body

[-]- 4x M4 x 8mm screws (see caution below)
[+]- 4x M4 x 6mm screws (see caution below)

[...]


[-]    Do not use screws longer than 8mm to attach the power supply. Longer screws may touch components in the power supply and short or damage them.
[+]    Do not use screws longer than 6mm to attach the power supply. Longer screws may touch components in the power supply and short or damage them.

Button head and pan head screws do not work with the crossbar. The bored out hole is too small.

I have a pin guide for using Micro Fit 3 connectors to help plan ahead when creating wiring harness. It's really handy if you use a rear panel with panel mount MF3 connectors (or if you just rewire your printer with them).

I doubt I'll fit this in before 0.9.9, but I'd like to include the file with the Molex Micro Fit 3 rear panels eventually.

I apparently failed to verify the mounting hole positions for basic LM2596 buck converters. I think they got messed up when switching to the auto-generated templates.

Regardless, the trays are incorrect. I will merge in a fixed to the main branch today.

The mounting holes for the Mean Well RSP-500-24 do not match the current Core files. It is larger than the current files, taking up majority of the lower base.

Bonus if there was a way to add an extra fan to the case to fool down this large PSU.

The only bay tray for the LM2596 right now is a full-sized tray and holds a fan.

Ideally there should be a single half-tray and dual full-tray.

Mark Rehorst has a Wago lever nut wire twister. That got me thinking of adding ways of using Wago lever nuts, particularly for splicing multiple fans together in the case.

• I figure that if a mount were added, 3-wire and 5-wire lever nuts will be the most commonly used.
• Lever nuts will probably also be used in pairs (+ and -).
• The simplest solution is to start with a lower bay tray.

I'm considering making mounting holes across from where the rear fans are. The lever nuts would fit in a holder that screws into the mounting holes. I'll start with the lower bay tray and gauge interest in built-in mounting holes after.

I looked through the files and saw TFT35 style panels but nothing as large as TFT50. Would also like a module for BTT UPS 24 to put inside the OmniBox. Also is there a way to add 120MM fan to the omnibox?

Mkdocs comes with support for a package called `mike1 that snapshots documentation and allows switching between versions.

I've been wondering how to beta without leaving old users in the dark, and this will solve it. Not sure how long this will take to setup, but this is a must-do before 0.9.9 for existing 0.9.8 users.

Screw holes for the SKR profile are the width of the board (~84mm), not the distance between the screw holes (~76mm).

This fix will be added to a hotfix release.

From this discussion:

When inserting the m3 nuts for the power terminal I would say that it really helps to use an m3x25mm to get the nut tightened into its recession by allowing you to poke the bolt through the hole and then snug the nut into place for the 16mms to go into after you remove the 25mm.

1. This will get added to the documenation.
2. I will look into improving that area of the case so that the "pocket" is more accessible.

The standoffs for the lower bay trays snap too easily. A 2mm fillet would fix this.

Also can punch out the bottom of the hole to save time and allow longer screws.

Discussed in #43

I've added a unified base for 0.9.9. This will be next after 0.9.9 is released.

Currently the display mounting holes are approximately 0.5mm too narrow on each side, so only two screws can be used to mount a screen at a time.

This issue only impacts the front main body.

I expect to have this issue resolved by 7/20.

Love this project!

Any way you could add support for the BIGTREETECH PITFT screens? Either the 4.3", 5", or 7" (but 5" or 7" preferred).

https://www.biqu.equipment/collections/lcd/products/bigtreetech-pi-tft43-v2-0-screen-board?variant=39840251936866.

Not sure if you'd keep the PI mounted to the screen, or keep it in the tray (probably tray? though that'd require a longer DSI cable, which should be fine.)

This would be nice. Requested by Level Fun Games via Twitter.

• Would require a new base version, but there is only one front base version ATM.
• Would also add more universal base versions...
• Maybe done as front panel option? Offer a version of the base without a switch?
• Gives the option of a reset button next to it (which won't fit in the base).

Targeting release after 0.9.9.

Parts throughout the case use a larger/smaller screw hole pairing. Screw goes in larger hole then threads into smaller hole, using the smaller diameter to bind the threads. Since this is used throughout the case, a short intro paragraph will be helpful.

Referencing my line of thought on Twitter:

First idea: Half-sized lower bay trays, to allow mounting up to four, smaller trays.

• You could still simply use two large trays and keep the extra room.
• This only requires adding 2 or 4 screw hole pillars that are otherwise unused.

Where right now the lower bay trays look like this:

[----------]   [----------]
|o        o|   |o        o|
|          |   |          |
|          |   |          |
|          |   |          |
|          |   |          |
|          |   |          |
|          |   |          |
|          |   |          |
|o        o|   |o        o|
[----------]   [----------]

Adding a few mounting standoffs would allow for more, smaller trays:

[----------]   [----------]
|o        o|   |o        o|
|          |   |          |
|o        o|   |o        o|
[----------]   [----------]

[----------]   [----------]
|o        o|   |o        o|
|          |   |          |
|o        o|   |o        o|
[----------]   [----------]

Which will let you still use the long trays, too!

This will only affect the rear main body; there is no particular implementation timeline yet except pre-1.0.

I am working on a solution, but the RSP-500 does not fit in the base area of the case. This affects all versions, including 0.9.9.

Edit: this does not affect 0.9.9.

Discussed in #49

Referencing my line of thought on Twitter:

Second idea: Remov[e] the MCU tray without removing the rear panel.

• Add two M4 screw holes to the rear of MCU tray template.
• Create a matching pillar in the rear body (like the front) for M4 screws.
• Remove the top guide rails for t he MCU tray from the rear body.
• Trays can then be inserted vertically and slide in the last ~20mm into place.
• Secure with four M4 screws and done.
• Allows replacing not just a board, but changing the model entirely (different tray) without removing the rear panel.

This enhancement is targeted any time pre-1.0, i.e. when time allows.

This will only impact the rear main body and board trays and is backwards compatible—as all updates to Core should remain in the future.

The Fusion 360 file for panel mounts is now incomplete and out of date.

It needs a pretty thorough overhaul, tbh.

• I've tested a Micro Fit 3 profile that's slightly wider and less awful if there's any elephant's foot present.
• Keystone jacks need to go in there, too.

I try to back up your 0.9.9 files as they change and I found that PSUs folder is now missing was there an issue with the Mean Well LRS-350 file? Second question is there plans for a Mean Well RSP-500-24 file? I have 2 of these headed my way to install on my 2 printers and really want to drop them in the Omnibox to get rid of the Mean Well LRS-350 I currently run. I can not open step files but I have included the drawing file from Mean Well hoping it has the mounting points included to help with file creation.

Thanks for all you do

Way overdue turning this into an issue. See most recent commits in 0.9.8.1 for latest. A slightly more refined version will be in the 0.9.8.1 release.

The git repo has license information, the packages do, but the docs don't. That should be fixed.

The trays are multiplying.

Many of the MCU trays support multiple boards (the SKR and SKR E3, specifically).

I have two working profiles for LM2596 buck converters in the Trays\Lower Bay folder. I have a third to add yet. MOSFETs and SSRs can be added, but will have to be by request or submission as I don't have any on hand.

Note: I want to avoid cross-pollinating brands/types of bucks on the dual-buck trays, as there's no way I can manage that many combinations.

Current Working Solution

This data should go in a Markdown README in each folder:

• Product name
• Image link
• Some kind of product page link

Links, in order of preference:

• A git repository
• A company's product page
• An Amazon or AliExpress link

Documentation does not specify.

• The lids in particular are missing readme files.
• Individual display mounts also lack a readme with BOM.

This is not a showstopper, but it does mean that the lid can only be correctly mounted one way and is not reversible.

I'm holding off fixing this until I hear feedback about using M3 screws for the lid versus using M4 (and possibly switching to M3 for the rear panel).

Something like this:

The TPU gaskets currently only cover outside surface of the fan cage. They should also cover the fan except for the intake/exhaust hole. As is they are only minimally useful.

I had a less-than-perfect test print that curled slightly. Instead of being able to neatly thread in the #6 screws, I pretty much stripped one.

I've cut out a bit of the area behind the screen that the screws thread into. See below.

Fixed version of the front main body will be in 0.9.9.

The Ender 5 Plus has a bed heater MOSFET that I'd like to mount inside the OmniBox of course.

It seems to be a Creality specific part. But fortunately someone on Printables created a mount that includes the Octopus which might help getting the mount hole pattern: https://www.printables.com/model/171559-ender-5-plus-btt-octopus-mosfet-mounting-adapter

Related issue: #11

Adding in support for multiple power supplies is straightforward, but greatly complicates the export process. Additionally, the PSU is the only component that attaches directly to the case, rather than through a mount.

PSU Specs

I looked up the most common Mean Well power supplies. The sides of their power supplies all mount at least two M4 screws on each side, evenly spaced from the midpoint (sometimes they are paired for four a side).

• Only one of the units that I looked at (all sub-500W) was too tall to fit within the 40mm tall base.
• Width and depth are not a problem.
• The screw spacing varies from 150-170mm between models.

Solution

I have a fairly simple solution in mind that would let the PSU slide into guides in the sides of the base pieces. They can be secured with M4 screws that would pass through the base walls.

With a few mm of space between the PSU and main body "floor", I could then add a number of vent holes and let air run above the power supply instead of below. The vents would add rigidity to the base, reduce weight, and possibly reduce print time.

I'm targeting the release after 0.9.8 to implement this.

This is a placeholder issue until a fit test is completed.

I am wanting to add a BTT Relay V1.2 to the Omnibox I used the file from this thingiverse as a blueprint and the bottom plate from "Lower Bay - DROK 5A Buck with LED" to start a file for it but I feel it could use supports for the screw posts and possibly wire ties like the "Lower Bay - DROK 5A Buck with LED". I attempted to keep the mounting post at the same height to fall into your ecosystem. Please feel free to make any and all changes to create this part for Omnibox ecosystem.

UNTESTED. My submission for the MKS Skipr

Wanted to use a spare MKS Skipr motherboard but noticed only BTT stuff was supported. Generated this version for myself, but wanted to give back to the project because it's so good. I have yet to print and test this, but it uses M3 heatserts for longevity.

MCU Tray - MKS Skipr - Heatserts.zip

If good enough, I hope this can be added to the project eventually.

Standard BOM SD card extension is too short. Testing was done with a longer extension.

Alternative is to rotate board. Will likely do this.

Link to a longer MicroSD extension.

Several things can be done to improve the experience for newcomers to the OmniBox website.

1. Add a few, small pictures near the top of the landing page to help with reader visualization. The only current pic is at the bottom and a render.
2. Add a version history/release log page for an at-a-glance update.
3. Explain stability guarantees between versions.

@weakfrank_ on Twitter pointed out the need for an upgrade guide with versioned docsites. I'd planned to do this, but sooner is better than later, particularly with versioning just being added.

I have a working design for this, but haven't added it to any parts yet. It's a little late in 0.9.9, but I can at least export the shape or make a front panel with one or two sockets.

If it doesn't make it in 0.9.9, it'll definitely go in the next point release.
