HDZero BoxPro/BoxPro+ FPV Goggle Multiboard Mount

This is a remix of https://www.thingiverse.com/thing:2741632

Added x3 features designed to interface with x3 unit spaces on a standard multiboard tile. Couldn't find one for this specific set of goggles.
The BoxPro+ is shown but the other variation [BoxPro] should also fit.
.stl, .step and the FreeCad file type are readily available.
