Ender 3 Pro Mainboard case

Custom mainboard case for Ender 3 Pro with space for a XL4015 buck converter.The original mainboard case unfortunately leaves no room for additional parts so I designed this modification with an overhang to the front which gives place for a buck converter which I use to power custom 12V fans for the mainboard and the hotend cooling fans.The sliding mechanism at the back is meant to take up a 52 mm long buck converter. You may want to check the dimensions of yours and modify according to your needs. It is tapered so the buck converter is meant to clamp in and stay in place. The top part is designed to slide into the rail and then snap in from the front. Yes, this is a bit fiddling but I did not want it to be even thicker as it is. The U shape is meant to lead the cables going to the hotend though (especially for direct extrusion mods).Please feel free to modify the design according to your needs.
