Summary

Mounting Bracket can be used without Lid and Lid Frame

The Mounting Bracket has holes for M3 bolts to mount to a front panel and M4 countersunk holes to tightly hold on to the SB50 connector.

The SB50 connector should be pressed in from the back and snap into the grooves on the sides.

Holes for the hinge have to be drilled out for a 2mm nail or whatever else you want to use.

I recommend printing everything at 100% infill.

Thanks Noggin for the SB50 model https://www.thingiverse.com/thing:3678539
