Anet A6 Power Supply Cover

It's my version of power supply cover for Anet A6 (bought in 2017 January).
Holes on the main wall are to easier use a screwdriver. The three big holes on bottom are to make easy access to manipulate with electric cables.
Rib with holes (inside) is to be passed through main power cord (stabilize it).
For assembly useful are the two M3 screws with nuts.
