I've been meaning to do something with my Tevo Tarantula power supply for a while and none of the power supply covers I looked at here quite did what I wanted, so off to Fusion360! I used this fused power socket with rocker switch: https://smile.amazon.com/gp/product/B06XKBRT9M/ref=oh_aui_search_asin_title?ie=UTF8&psc=1 And this power supply: https://smile.amazon.com/gp/product/B004MS4Z70/ref=oh_aui_search_asin_title?ie=UTF8&psc=1 So it should work with any switch/power supply combo that have the same dimensions. I also added some square 'feet' on the design to add some stick on silicone pads for extra grip. The case fits well with just a pressure fit, though you can secure it to the power supply with some short M4 screws if so desired. The hole for the power output is minimal; I just needed to fit the 12v wire through it and capped them with standard blade connectors. You'll need some of those anyway to wire the plug to the power supply anyway.
