About this 3D model

This is a coaxial mounted thrust bearing mount for the Z axis steppers of a Trinity Labs Aluminatus printer. I mounted it to studs that run through the deck of the printer. There are clearance pockets on the bottom for the nuts that hold the stepper in place. The coupler can be adjusted through the front and rear openings. The design is in OpenSCAD and uses parms for most things. I've added an update that uses a true thrust bearing, in particular a 7x13x4.5 miniature thrust bearing. I added a screw on cap to retain the bearing.
