Stepper Motor Gimbal (Compatible with Zhang Datou Stepper Motor)

This is a 2D gimbal print designed for Zhang Datou stepper motors

Note: Bearing shaft, 60mm copper pillars, and 42 stepper motors need to be purchased. The model is only for ease of assembly. It requires one 5*10*4 (inner diameter, outer diameter, thickness) bearing, three M3 screws longer than 20mm, and several M3*6 and M3*10 screws with corresponding nuts. Because the stepper motor itself has some weight, I did not install a bearing shaft and instead used 6 M3*10 copper pillars.
Additionally, during 3D printing, different printers may have different tolerances. The dimensions in the file are adapted for my printer and may need modification.
M3*6 32 (screws)
M3*10 4 (screws)
M3*20 3 (screws)
M3*10 3 (copper pillars)
M3*60 3 (copper pillars)
M3 8 (nuts)
5*10*4 1 (bearing)

All files converted to STL are for printing; print two of chassis 2 and the flange shaft, the others are for assembly
