Ender3CoverSpacer

Implementation in Fusion360 of a cover spacer for the ender 3 electronics box to fit when when you have Trinamics TMC2130 drivers with heatsink.
The fusion design is fully parametrized, all dimensions can be adjusted, look for 'haut' parameter for height.

Inspired from https://www.thingiverse.com/thing:4611015 and https://www.thingiverse.com/thing:3798051, but with new quotes as the screws are not exactly symmetrically placed.
Rear screw support should rest on the lower transversal profile of the Ender3.
