About this 3D model
I couldn't find a bed plate holder that could be screwed down to a shelve or to the wall, so I designed one. It takes 4x #6 screws (4mm diameter ish) at least ¾ long, longer is best if mounted to the wall. The length fits between the ears of a Prusa bed plate, larger plates fit too. The slots have an incline to hold the plates in if it's wall mounted.
