SlotLock - A locking wall mount

I needed a strong wall mount that would hold my coat hanger on the wall without visible screws. I first saw this design: Strong Universal Wall Mount, but didn't like the idea of my children disassambling the coat hanger by accident. So I designed a wall mount that features a DIN EN ISO 7045 M4x25 screw and a M4 nut to fixate the wall mount once its installed.The slot and insert are meant to be fixated by a wood screw. The biggest screw possible is a 5mm with countersunk head, but smaller ones should not be a problem.Print InstructionsI suggest you print in PETG with a moderate infill (since this design is mostly walls anyway) and a layer heigth of 0,2mm.

I suggest to print it like this:Serving suggestion (wood plank not included)I used this wall mount to build a coat hanger for my kids from leftover wood from a US pallet.This is how it looked
