Remixed it specifically such that it fits with the PSU Rear Mount on the original Ender 3.
The length has been increased and also made it flat on the sides so that it doesn't interfere with the the PSU Mount.
Made the Rubber Feet indent smaller. The one I used were from amazon and the indent is sized for them 25x25x4.5mm (You can also cut the original feet to size and glue them on, I just didn't want to apply new glue :p)
Tight fit, it won't move so that's good but just lightly spray it with water and a hit it with a rubber mallet if it doesn't go in easily.
