Issues with Clip 2n125 Clip 3n20 about sawppy_rover HOT 3 CLOSED

Great tips, @adamgreen. I would like to add the following:

• If the clips are too thick at initial layers, the first layer height settings need adjustment. Search online for "3d print elephant foot" for more information.
• If the clips are too thick throughout, try reducing the extrusion rate (aka flow rate aka extrusion multiplier). Normally under-extrusion means layers that don't stick very well together, but layer adhesion isn't as important for these clips.
• If the clips sharp corners are wobbly, try a slower printing speed. Search online for "3d print ringing" for more information.

If none of the above describe the problem you encountered ("not printing smoothly" can mean many things) please attach an up-close sharply focused picture of the printed results so we can see all the necessary details.

Oh and finally, never underestimate the usefulness of sandpaper!

I printed mine out of PETG on a Prusa MK3S, the same used for the rest of the parts. I did hit a few issues:

• I needed to print a large number of them at once so that each layer would take long enough to let the previous layer cool before starting the next one. Looks like I printed 20 of the 3n20 and 50 of the 2n125 ones according to the .3mf files I still have kicking around from those builds.
• I used a textured PEI surface for most of the other parts but the clips just didn't have enough bottom layer surface area to stick reliably to this surface so I switched and used my smooth PEI surface for the clips instead.

I still got some blobbing and a bit of warping but I still ended up with enough good ones to put together my printer. They don't need to be perfect to do the job needed and they can't really be seen anyway. Actually some of the oddness in the shape made them fit a bit more snug in the channel anyway :)

Thank you @adamgreen and @Roger-random. Very insightful and I will keep these tips in mind.
