Hi, I designed an adjustable motor holder for NEMA 23 motor.

Checking the dimensions before printing can be good, some manifacturers use lighltly different ones, so that you wont waste filament :)

Things you will need for assembly:

8x M4 Screw and nuts to hold the plate to the holder to be able to adjust the height and the motor to the plate

4x M4 Washer for mounting the plate to the holder

4 Screws to mount it at whatever you want :)
