Depth stop for drill-bits

I took some inspiration from mishkin2's model and made my own version for M4 hex nuts (to be pushed in) and made versions from 2, 3, 4, 5, 6, 8 and 10mm.

I also made a parametric .f3d where you can change the diameter of the drill and it gives you the finished model.

For each printed model you need a M4x12mm screw with internal hex and a M4 hex nut.

Assamble as shown in the picture and start drilling.
