E3D PZ board mount for Voron0.2

A backpack for Voron0.2 toolhead to securely mount an E3D PZ board to the toolhead. The board is mounted behind the toolhead which is out of the way of the toolhead, possible toolhead boards and other modifications.

While the model is borrowed from MiniSB, it works well with other toolheads that use the same toolhead carriage as MiniSB, like DragonBurner etc.

Print using regular Voron print settings. Board is mounted with the M2x5 bolts that come with the PZ board. The screws will thread straight into plastic so do not overtighten the bolts.

Secure the backpack to the toolhead using M3x12 buttonheads. Ensure the board is properly seated, as there's limited clearance under the mount.
