This is a stub for the Graber i3: https://github.com/sgraber/Graber [DXF and SketchUp files available]
Laser cut parts can be ordered here: http://twelvepro.com/index.php?route=product/product&path=66_59&product_id=52

The Graber i3's design is uniquely suited towards building it with a laser cutter or even a simple CNC cutting machine, such as the Shapeoko. It derives from the original Prusa i3 design, and replaces all 3D-printed parts for completely wooden ones.
Build volume: 200 x 200 x 200 mm
Bill of Materials
This list may be incomplete!
The metric figures below are meant to be equivalent to their imperial counterpart - they might not be an exact fit. M3 nuts will be to small for the provided slots (thus the strikethrough); M5 nuts would be wide enough, but the screw holes only have a diameter of 3.5mm. One possible solution is to use M3 nuts+M3 washers. Find some M3 washers that have an outer diameter of 8mm, and use one washer per screw to make it a secure fit.
If you are laser-cutting the wooden pieces yourself, you will need two 810 x 460mm pieces of 6mm thick MDF.
