This is a rear electronics enclosure for and Ender 3 Pro, modelled for the specific purpose of containing the MCU using a standard Creality board footprint, a Raspberry Pi with its standard footprint, a random buck converter that I had handy, and an U2C USB to CANBUS converter module.
All of the cables are internal for neat appearance and dressing. There's no access to the SD Card slot, but I don't print from the SD Card anyway. There are two keystone openings available if you want to expose the Ethernet connector or a USB connector. You'll have to find a pretty low profile USB keystone, though, because of possible interference with the MCU.
Note: this is a remix; I can't find the original model, but I'd be happy to credit him or her once I can find it or he or she can identify themself.
Note: you'll need to use several M3 heat set inserts to assemble this. If you've been afraid that heat set inserts are a pain in the neck, just try it. They're great and they'll change how you design things in the future.
I've also provided the Fusion 360 file, as well as a STEP file for those who like to remix without yucky meshes.
This enclosure works nicely with my remixed front-mount power supply. Click my profile to see my other models to find it.
