Raspberry Pi HAT mounting kit

This are the 3 components for creating a mounting kit for a Pi's Hat. After lots of tests, I achieved to make something that is screwable. It is working for me, at 0.06 layer height (minimum for my printer), and 100% infill, printed with PLA (other material could make it even more robust).

All the parts are customised from "NUT JOB | Nut, Bolt, Washer and Threaded Rod Factory by mike_mattala", so they can easily be modified.
My spacer size was 16 mm, and the parameters are:
