TR8-4 Z-Leadscrew/motor cover

I switched out my Z-motor setup(motor/coupler/leadscrew) to an Integrated motor/leadscrew 

I thought I needed a dust cover for the motor/screw junction, so here's my attempt.

I added the Fusion 360 file

I printed one in PLA and it spun freely…I printed the one in the picture in ASA and it turned freely with a little drag

If you need to adjust the thread clearance, there's two press/pull features to edit the clearances in the Fusion 360 file
