Printed Parts

Changelog

5/9/17 – lead screw compatible XYZ

7/13/16 – New Rollers

5/25/16 – New middle and Z-Axis assemblies

4/24/16 – New corner assembly

Recommended; PLA for dimension accuracy, 3 perimeters for through hole strength. I have a .4mm nozzle and print at .26mm layer height, just personal preference. I do print slow for strength, so your prints could be faster.

There are 3 different sets of printed parts. They fit 23.5mm, 25mm, or 25.4mm (1in) Outside Diameter conduit/rails/tubing. Steel hardware store EMT conduit is awesome and inexpensive, an upgrade would be .049″ wall thickness stainless steel tubing. It is more rigid and smooth, but also much more expensive.

Please measure your rails before printing. 23.5mm fits 3/4″ EMT conduit in the US. Anywhere else you must physically measure first, some things are sold as Inside Dimension (ID) (conduit), or Outside Dimension (OD) (Tubing).
