3D Printed Housing using PA12

The housing parts are professionally printed with nylon for maximum strength and precision and higher temperature resistance.


Use the supplied studs to replace the 4 screws of the stepper motor and use them as additional mounting points.

Be aware the stepper motor threads are made of Aluminum, and they are delicate.
Don’t use too much Torque to tighten the studs.

They have a M3 thread with 4 mm depth.
