MPCNC F NutTrap with cover

I was sick of all the Z tube nut traps that were either off by a few mm's between the holes, or had nut spacing bigger than the M4 nut for a metric F model MPCNC.

So I designed my own which also includes a slide lid to secure the nuts from falling out when you try to mount them (rather than gluing them).

Tolerances are good enough that the lid will slid in/out with hand force, but will not fall out.

Tested with the F model tool mount from original design.
