Overview
The Parametric Printrbot Variant needs a better name. It is inspired by the Printrbot, but is a complete redesign in OpenSCAD to be more robust (without the loose press-fit mountings), but still extremely simple. It is being designed for use with 6mm smooth/threaded rods and NEMA14 motors like the ones used in the Huxley design, and LM6UU bearings for linear motion, though its parametric nature means that NEMA17/M8/LM8UU versions will also be possible. STLs can be found on thingverse, the source is on Github, and the latest updates/previews can be found on Whosawhatsis' Google+ page. This design is a work in progress.

Parts
In addition to the printed parts, the following parts are required (this is a tentative list, and the parts WILL change before the design is complete):
- 4 high-torque NEMA14 motors. Sources:
- Pololu
- Zapp Automation
- Waterott for 20 oz-in non-dual shaft in Europe
- 3 pairs of 6mm smooth rods (measurements will depend on desired build volume).
- McMaster-Carr
- Fastenal
- ebay
- These can probably also be found locally.
- 2 pairs of M6 threaded rod (measurements will depend on desired build volume).
- McMaster-Carr
- Fastenal
- ebay
- These can probably also be found locally.
- 10 M6 nuts.
- These can be found locally.
- 2 M6 nylock nuts.
- These can be found locally.
- 8 M6 washers.
- These can be found locally.
- 11 LM6UU linear bearings.
- 3 623 bearings.
- 13 10mm M3 screws.

- Aproximately 13 M3 nuts and washers.
- These can be found locally.
- 1 sheet of MDF or other flat material (measurements will depend on desired build volume).
- You can buy this locally and cut to size.
- 2 belts
