Rear Mounted Stock Ender 3 Electronics Case

I wanted to move the electronics for my Ender 3 to the rear so the USB cable is not hanging off the front of my printer. I'd seen other complete rear case options, but it felt wrong to just discard a perfectly good metal case.

Then I realized that the printer is symmetric and the 40x40 extrusion and electronics case could be rotated 180 degrees. However, once I attempted this there were a few issues.

1. The electronics case conflicts with the Y axis limit switch bracket. So I designed a new bracket which is available here.

2. The Z axis limit switch cable is too short. So I extended this cable, and also moved the switch to the right side to be closer to the electronics.

3. The holes in the end of the extrusion under the power supply are not tapped.

Another benefit to this mod that I did not realize until it was complete is I can now access all four bed leveling knobs easily from the front of the printer especially with the squash ball feet installed.

Note: I also moved the control panel to the left side to reduce the overall width of the printer and make it easier for me to access and view from where I have my printer located. Note this is unrelated to moving the electronics to the rear.
