Ender 3 Meanwell PSU Mount
Description
This is a replacement PSU mount/cover/bracket for the ender 3 pro's MeanWell power supply. #Features * Moves the AC power connector to the back * Has a mount point for [an inexpensive 5V relay board](https://arduinomodules.info/ky-019-5v-relay-module/). This relay can only handle 10A, which is insufficient for switching on the 24V side of the PSU. So it has to switch on the mains-side. * Extra room for whatever else you may want to throw in the enclosure. I threw in a 5V USB adapter that won't be switched off by the relay. This powers my relay (I just directly soldered power cables to the relay board) and also sends power over to my raspberry pi via the 3 wires on the relay board. It's printed in 2 parts to: * Save filament with very few overhangs * Provide easy access to the electronics The 2 parts are connected via the PSU, the power connector, and an additional bolt for stability. #Additional hardware * 1x M3 bolt that's at least 6mm long for holding the 2 pieces together * 4x M3 bolt that's 4mm long to mount the relay board. * Stock mounting bolts/screws for the power connector and power supply. #Additional notes Apparently different ender 3 pros have different clearance between the PSU and the bottom aluminum extrusion. With the stock PSU cover, there was 16mm of clearance between the bottom of it and the bottom aluminum extrusion. So if yours has this clearance, it'll probably fit on yours as well. #Remix If you'd like to remix this, I designed it with OnShape. I'm relatively new to OnShape, so the model might have a few things that could have been more parametric. https://cad.onshape.com/documents/ad9a8798b97bf5f1e16d44e8/w/9b5bfefa12370359a4300719/e/d01339c257c3ad5cb57913de
