Nut lock for prusa i3 heated bed regulation

Designed this so i can just regulate the heated bed with a screwdriver, without the need of a wrench. I used nylock m4 nuts with m4 screws.

The desing comes with 2 locks, so you only need to print 2. It does not need supports, they are built in the design, just peel them off the bottom and cut the 4,2mm hole.
