Ender 3 rear Pi case (all in one, universal rear electronics case)
thingiverse
I really like Teaching Tech's rear electronics case. However with various people mentioning that the relay he used was not powerful enough, I went searching for one that was. This was way bigger than the relay be used, so the case needed modifying to fit the new relay. I also adjusted the buck converter (which powers the Pi) mounting holes to fit the buck converter I used. In order to make the bigger relay fit, I've also moved the Pi over by 7mm. Lid can be found here, under left lid: https://www.thingiverse.com/thing:3688967 For wiring, please watch Teaching Tech's YouTube video, however I have included my attempt at a wiring diagram. I think using the diagram and picture should be enough to figure out what's going on. Please find links to the parts I used below.
