Plunger adaptor

I designed this part to be able to assemble this pincab plunger: https://www.smallcab.net/lance-bille-p-753.html

with this plunger mount:

As the nut would prevent using the original mount, my design allows to use the nut by adding a 5mm plate which also acts as a holder for the hexagonal nut.

It's not a remix, I designed it from scratch using the measurements of the original Bally mounting plate
