While building my Lack Prusa enclosure I found out that the door knobs would fall off sometimes. I looked at various remixes here, but most of them used 3D printed threads and they didn't work well for me, so I remixed the original to use M4x4 set screws. They are easy to insert due to the holes on the angled part and keep the knob secure in place. I also added a small edge at the end (where the vertical edge of the plexiglass rests on the knob) and put the magnets inside, which means that you don't need to superglue them anymore, but you do need to add a pause at 9.20mm when slicing the STLs! When the print is paused add the magnets and then resume the print. I also added the Fusion 360 model (.f3d) for easy changes.
The remix is designed to use the same magnets as the original (20mmx6mmx2mm), although I only had 20mmx5mmx2mm and they worked perfectly fine.
Printed at 0.2mm layer height with 3 perimeters. The infill isn't really important, 20% should be more than enough.
