Prusa i3 heat bed nut holder

Heat bed nut holder to replace the wing nut with M3 nut. It holds the M3 nut in place and allows adjusting heat bed single handed with a hex driver from above.
There is a deepening for washer.
Print these out and cut clip height to suit your heat bed height. This printer has 8 mm acrylic plate.

This revision should print out nicely and the nut should have a snug fit to hold the nut in place. I printed these with PLA and for me they work nicely.
