Optimus Pi

cults3d

This started as a 'flight of fancy' vanity project to create a stand alone controller housing and PSU for a 3D printer. It rapidly got out of hand and ended up as the monstrosity you see here! It's designed around a Meanwell LRS-350 PSU, SKR 1.3, Pi 3B+, a offboard mosfet to control the heated bed, two LM2596 buck converters and a single XL4015 buck converter to supply a solid output for the Pi. There's also a housing for a 80 x 25mm fan to give lots of nice, silent PSU cooling (cutting the PSU cover to suit is recommended), and perched on top is a 60 x 25mm fan cooling the controller, Pi and the stepper drivers. I have actually printed and assembled the entire thing, so pictures will be added as I put it all together again as I wire and commission it. You will need a lot of fixings! This is a ridiculous and pointless exercise in seeing how unnecessarily complicated you can make some thing that does a simple job. The parts print with little or no support and are already oriented to print easily. I hope you have as much fun with it as I have. The files are up, but keep an eye on this description as I will be adding extra info. If you are buying this before I've added the extra info then please message me and I'll try and make sure you get any updates. A Pi 4 mod has been added. You need to print the Pi_4_Cover instead of the Pi_Cover in the Controller_Shell folder and Pi_4_LHS_PCB_Mount instead of LHS_PCB_Mount. I've added the STP files for the entire assembly, one for the Pi 3 version and one for the Pi4.
