MPMD (Mini Delta) bed clips bottom adjusted

This is an elegant solution of mpmd adjustable bed.
Adjusting works great. Its is hidden, but allways accessibble.

You need:
- 3x M3 screw 3x16mm (or longer then 16mm)
- 6x M3 nut
- some rubber
- Some MPMD legs to get space under the printer
- (!) 12mm holes in the bottom plate/cover (I printed my own - on bigger printer, not possible on MPMD. Or you can drill the original plate.)

The screw is mounted fully in the bed! Adjusting is done by the nut rotation.
You can adjust it so there is no click, almost no movement of the bed to get "red" :)
