This repository aggregates resources for people with very limited resources (like Cuban makers) to build their own 3D printers with the minimal number of components and material. Solutions cover a wide range of possibilities so that people can get started quickly according to eventual availability facing scarcity.

The key value of this repository are:

• A list of tools needed in a Fablab, both generic and serving to specific purposes
• A curated selection of parts, instructions and resources compiled across open source projects needed to build digital manufacturing tools
• Parametric designs of each tool including:
  • Detailed geometry of single parts
  • Bill of materials (a.k.a BOM)
  • Parameters for satisfying a wide range of models and product families tested and used in practice to assemble real machines
  • Parameters to position machine tool at a given spatial configuration

The following tools might help in setting a Fablab up:

• 3D printers
  • Prusa i3
    • P35X70 a DIY alternative using Al extrusions easy to buy in Cuba
    • ANET A8 clone a DIY alternative using E2040 profiles, Marlin, and RAMPS
    • CoreXY octanorm implements a CoreXY mechanical system using Octanorm extrusion profiles for the frame.

The following DIY parts may also be manufactured for assemblying machines.

• Bearing
• Extrusions
• LCD case
• Pulleys
• Spool holder

See project wiki for further details.

Some of the features implemented in this project require the following libraries installed in OPENSCADPATH:

• NopSCADlib

• DIY RAMPS board.
