Knob Factory

A parametric OpenSCAD design with 46 documented parameters that allows to generate many kinds of knobs. Examples include: small knobs for potentiometer inputs; knobs for turning the extruder or an axis of the 3D printer; water spout knobs etc..

This is a remix. The Thingiverse search for selecting the base design is broken atm, so I have to put it here: "Parametric Potentiometer Knob with OpenSCAD" by steevecooley, https://www.thingiverse.com/thing:20513

You should be able to use this in the Thingiverse Customizer. Otherwise use it in OpenSCAD directly, which is preferable anyway (and OpenSCAD is free!). When using it in OpenSCAD, the `.json` file provides configurations for some of the examples from the screenshot and for an Ender 2 extruder knob.

**Parameter list**

* knob_radius_top, knob_radius_bottom
* knob_height
* knob_faces (number of faces on the circumference)
* shafthole_radius, shafthole_height, shafthole_faces, shafthole_cutoff_arc_height (to create D shaped
