Summary
Case for the Pixy CMUCam5 made by laser cut. It consists out of plexiglas of 3mm and 6mm thickness and two 8mm distance sleeves also made by a laser cut of 8mm plexiglas.
Use 6 x M3 10mm to stick the Pixy and assemble the case.
Please note, that the case on the actual images has a different front plate, since the design of the lens mount was changed in order to extend the lens focus to smaller object distances.
