NEMA 17 Stepper Mount to Aluminum Extrusion
thingiverse
The previous setup's stepper mount was updated to incorporate NEMA 17 features. The primary goal of this upgrade is to expand the motor's range by relocating the mounting system backwards, creating sufficient clearance between the coupling attached to the shaft and the lead screw. This newly designed mounting solution effectively utilizes the substantial width of the 2040 aluminum extrusion (measuring 20mm in width and 40mm in depth). The printed results in PLA have proven satisfactory; however, it's necessary to carefully enlarge the holes drilled for M5 screws due to a slight tightness fit.
