This page collects suggestions for useful things for a RepRap machine to make. If you are a designer and wish to help out the project, pick something from this list (or WhatWouldYouMake), design and test it - then add it to the List of available files and remove it from here.
Suggestions
Mechanical components
- Gears and geartrains
- Tracks and bogies
- Wheels systems enclosures
- Battery boxes for standard battery sizes
- Pulley wheels and blocks
- Gaskets
- Chain

RepRap 3D printer
- RepRapSlurryHead
- Recycler and filament extruder
- RepStrapMini (smaller version, specialized to make loan modification only RepRap parts for full-sized machine. Easy to give out. Palm sized?) (Mini-Mendel and Bonsai RepStrap are big (pun!) steps in this direction)
RepRap associated technology
- CameraScanningHead
- TouchProbeScanningHead (Scanning)
- Generic keypad
- Automated part unloader -- see thesis by Øivind Brockmeier: "AUTOMATED LOADING AND UNLOADING"[1]
- Adapter plates to mount a RepRap in a "cube" for http://cubespawn.com/ . Eiffel and doboz might be able to fit with some very minor tweaking.
