These are brackets that I have made to mount Nema 17 stepper motors to a small milling table.
The “big part” is the main part. I have uploaded one with support material. The cylinder in the middle must be removed after the print. See picture.
I also uploaded a “big part” without support material for people who want to generate their own.
The small peace is to connect the shaft of the motor to the turning wheel of the table.
I printed this part in PET-G. This material is good in flexing a bit, which is an advantage if the motor shaft is not precise aligned. :-)
