No Supports Ender 3 S1 mounting bracket for "Malolo's screw-less / snap fit Raspberry Pi 4 Model B Case & Stands"

I was tired of my pi4 case just laying around next to my printer and so I designed a little bracket to clip it to the side of my Ender 3 S1. I'm not 100% sure which Ender models it will fit but it should fit any of the models with the 40mm square tubing frame. I also included the STEP file in case  you want to do some minor editing to the file. The tolerances in the model are specific to the accuracy of my printer. 

I didn't use a brim when I printed it in PLA and PETG, but if I were to print it again I would use a small brim (like shown in the second picture). The tight corners of the first layer had a little trouble sticking nicely even on my new PEI bed.

I used 4 perimeters to give it enough strength not to break it while clipping it on. You could probably get away with 3 if you wanted. 

For installation, I had to lay the top flange onto the top of the frame rail and try to line up the notches on the underside of the flange with the corresponding notches on the frame rail and then used a decent amount of force to clip the bottom side in. It snapped right into place a felt great once it was on. it can also slide back and forth on the rail to wherever you want to place it. Once it was clipped onto the frame I popped the Pi4 case into the larger side and it went in with relative ease.
