This is a remix of CheesePatrol's object, the Qidi Tech 1 - magnetic door stop.

Attaching this object underneath the printer's handle and inserting magnets into the opposite end of the object creates a magnetic latch that holds the Qidi Tech 3D printer's door shut and also stops it from swinging inside the 3D Printer.

The neodymium magnets that I used were smaller in diameter at 6.35mm than the 8mm in the original object, which required a little re-design on my part.

I used OpenSCAD to import CheesePatrol'sqidi-door-magnet-outside-mount.stl, fill in his magnet holes and hollow out a smaller hole for my 6.35mm magnets.
