Printed Parts

There are 3 different sets of printed parts C-23.5mm, F-25mm, or J-25.4mm (1in). The measurement is for the Outside Diameter of the conduit/rails/tubing. 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). Bummer

Steel hardware store EMT conduit works well and is inexpensive, an upgrade would be .049″ wall thickness stainless steel tubing. Stainless Steel tubing is more rigid and smooth, but also much more expensive.

Recommended Print Settings; 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 35mm/s, so your prints could be faster.
