Cục chặn cửa thông minh (Door Stop)

A door stop that mounts on the underside of a door.  It requires a minimum clearance of 6mm under the door.  Its location is movable along the underside of the door.  It fits doors from 30mm to 41mm thick.  The bumper should be printed from TPU to provide some shock absorption.  The other parts can be printed from a variety of materials.

I found that the TPU bumper and all of the threads prints well with a layer height of 1.5mm.
