Monoprice Mini Delta Glass Bumper and Shield

thingiverse

I really liked Bufftea's design for a glass hold down for my Monoprice Mini Delta, however the bumpers would still shift a little bit on my printer. In order to eliminate movement, I added two holes on each bumper to hold a 3mm thick by 6mm diameter rare earth magnet. The magnets hold the bumper very securely. In addition, while the original design provides some protection from debris falling into the inner workings of the base, I added a removeable taller shield that snaps into the magnet holes. The holes hold the shield very well. The bumper should print just fine with no support if oriented upside down (as in the file) while the shield should be printed vertically using supports. This gave the best results for me.
