Removable bed plates holder, wall mounted or self-standing

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.
