This is a collection of remixes of the listed Things, with some ideas added from others I suppose. Thought it was time to get them all together. I made these for my Ender 3 Max, but they also fit on the Ender 3 Pro and the original Ender I believe. Not sure about how they fit on the V2, but someone should try.
Added a few 3mm nuts and bolts and had to use a longer 10pin Display cable and a longer 5pin TFT cable.
I'll update this as I add the parts.

1: The main control board that fits in the inside edge of the left wing was always a pain in the butt, having to turn the machine upside down to get at. So I took the case submitted by ilnaij (#4470558) and essentially mirrored the outside of the case so I could fit it on the outside edge of the left wing. I also opened an 80mm hole for a larger fan to mount on top of the cover and added a modified fan shroud by jimb15122 (#1972504) to stop things falling into the fan.

2: I altered the PSU cover by blaahen (#4764552) by enlarging the 80mm hole a bit and added the ender logo by tom666 (#3078936) just below it.

3: I made some small adjustments to the display cover by michaelvs (#4168682) and added the ender logo to it. The back was altered to allow the 10pin cable to get plugged into the EXP3 connection and opened up the spot to allow the ESP-01S wifi module to get plugged in.
