About this 3D model

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. More holders for Kupper pegboards: Kupper Collection
