This is a Remix of the Case rear from Chaendar.
The Tevo Tarantula Extended case (minor remix).
It is just mixed up for a 48 x 28mm Power Switch.
Sketchup File included.
2018-01-22 : Make the hole for the Power Plug a little bit more to the top, make the screw holes larger and more far away from the power plug.
It should be right in place now.
