Prusa LACK Enclosure doorknobs and stop with set screws and slots for 10x3 magnets

I recreated the original doorknobs from the LACK enclosure, but I included set screws to secure them in place, and I included magnet slots for 10x3 disc magnets instead of the bar magnets from the original. I also included a hole underneath to push out the magnets (though it would also be easy to draw them out with another magnet).

Recommended print settings: 0.1mm layer height (for the threads), no supports
