Apply first coat, Allow to cure for 5mn Buff the excess with a microfibre towel Allow to dry at last 30mn Apply the seccond coat Allow to cure for 5mn Buff the excess with a microfibre towel Allow to dry at last 30mn How I Designed This Why this knob shape ? I wanted a simple and understandable shape oriented to function. I believe if you keep things simple, It should fits in a large variety of situations. I wanted that dimensions fits both a child or an adult hand, but keeping the knob as small as possible, to prevent clothes catching if you walk near the knob. I wanted it small and elegant. So it can fit small to large drawers. I designed the largest possible notch to allow a good grip without weaking the part. I've tested it on large and heavy drawers up to 60mm (24") wide with no issue. I believe the knob is strong enough to drive larger drawers, but maybe you want to install 2 of it on large drawers for more comfort. The last improvements was to make it smooth to the touch and comfortable. This is the V2 attempt, and probaby the ultimate one, because I've nothing to improve on it.
