# Knobs
This repo contains a parametric knob generator for quickly generating tactile knobs for standard metric bolts.
## Example
```scad
use <./scad/knob.scad>;
knob(H = 10, D = 14, DEPTH = 4, BOLT = "M4", TYPE = "hex");
```
This will generate a knob that is 10mm high, has a diameter of 14m and takes an M4 hex bolt that sits 4mm from the bottom.
An M4 bolt can be dropped in, or an M4 nut.
