Ender 3 Z Brace, no extra hardware required

thingiverse

I created a design that connects the power supply housing to the frame without needing extra hardware like screws and t nuts. This was necessary because I didn't have those components available. The fit is deliberately tight, so it may require some cleanup before it works smoothly, depending on how well your printer is tuned. In my case, I had to shave away part of the brim to get it to fit properly. I printed this at a layer height of 0.28 with three walls and 20% infill. Additionally, I used a brim to prevent edges from lifting up, as I've experienced issues with that in the past.
