Was thinking of mounting a Pi/Buck converter to the back of the Ender 3 V2, where the PSU in previous models used to be, to act as both a sleek(er) mount and a bracer to further stabilise the frame. I have already created a Pi case using this idea, however I abandoned this specific design. This should still serve as a good bracer, though.

Rails remixed from flickeringsight. Railless version will require your own nuts and bolts.
