Tronsmart U5PTA 54W USB charger case wall mount

This is my first design for 3D printing using Fusion 360, ts a pretty simple model.
I wanted to mount my USB charger up but don't want to put double sided tapes onto the charger itself so I designed this case to mount to charger. Was going to use double sided tape but I just run out of the thick ones and too lazy to buy more so I added the screw holes to screw it on my pencil holder.
