TronXY p802 / p802ma control board + Orange Pi One enclosure

thingiverse

A simple half-case designed to shield and cool the Melzi board stepper drivers and the OPi One. Notably, Orange Pi One fits perfectly into the top two screws making it a smooth upgrade to run Octoprint on. Please note that this case does not provide significant mechanical protection as there are only two points where the cover is screwed to the frame. Furthermore, it is a half-case, not covering the entire Melzi board, since the priority here is to shield the OPi and cool the stepper drivers. Additional hardware used includes: - 40 mm fan (either 5V or 12V, depending on what you want to power it from), mounted on the inside - 4-6 16 mm M3 screws - 2 15 mm F-F M3 spacers - 4-6 M3 nuts Firstly, mount the OPi onto the top two screws. Secure it in place by screwing on the two nuts. Then, attach the spacers to the nuts providing necessary spacing between both boards and the cover.
