DIN rail mounts for printer controller boards

DIN rail mounts for combinations of the Duet 2, Duex2, Duex5, Raspberry Pi, Bigtree Tech (BTT) GTR. Heavily inspired by Voron Design, but intended to use heated inserts instead of self-threading screws.

Designed to accept McMaster-Carr P/N (94180A331)[https://www.mcmaster.com/94180a331] in the mounting plates.

Controller board mounting plates have three sets of mounting points but will be perfectly acceptable with two. Middle point provided for the OCD.

RaspPi mount uses push-fit pins to avoid having to order M2.5 hardware. All indication so far is that this works without issue.

RaspPi and GTR parts printed and tested in PETG. Duet parts untested, but based on dimensional drawings provided by Duet3D.

A 250mm/~10" DIN rail will easily accommodate either a Duet 2 + Duex5 or a GTR+Pi combination.
