Yet another base plate for your Raspberry Pi. Doesn't do anything special; just keeps the board elevated and provides some more convenient mounting holes.

Outer dimensions are 64mm by 96mm - or 8 by 12 LEGO studs. The holes in the corners are sized and aligned to press snugly onto 1x1 LEGO pieces. (A little filing may be necessary to make the fit smooth.) Of course, they'd work fine with screws and washers too.

I printed mine in clear PLA on my Printrbot Simple. 3 perimeters, 0.15mm layer height, 0.2 hexagonal infill.
