This is my design of a charger wall mount as I am now lucky owner of an electrical bike. And the charger doesn´t provide anything to hang it somwhere tidy on a wall or somethig. I made the thing a little larger than needed, so maybe other chargers or switching power supplys you want to have hanging somewhere will fit into there too.
To fix it on a wall use 4mm pan head screws. At each side there is a small clip to put the plugs for easy access when not in use. They are relative thin and if you don´t need them, cut them away with a hobby knife.

Printig: I did this in PLA, 0,2mm layer, 0,4mm nozzle - supports are not really needed, I printed them by mistake...

Have fun printing, editing or remixing this!
