Door knob and backing plate to replace locks for Kupper cabinet doors. Felt that the locks with keys were cumbersome and always on the way.

Backing plate has a slot for washer, 1.4mm deep, diameter 14.90mm, but the washer is not necessary. Knob measures 40mm diameter and 15mm depth. Two versions for the knob, one with a hole for M4 brass insert (hole diameter 5.4mm), one that fits M4 screw straight (hole diameter 4mm).

Knobs work well with 0.20mm strenght, so 6 walls. Backing plate needs a support and 8 walls to be solid.
