This is just a bracket inspired in the same fashion of the brackets mounted with VHB tape at the back/bottom of the v0.1.
I added the Voron logo but If you want it without it, you can always add a tiny cube in the middle of the model (PrusaSlicer or SuperSlicer).
The idea is to stick VHB tape to mount it where you want, and use self-tapping screws for the pi zero :)
