Big Knobs, Knurled and Labeled, with a Set Screw

This file is a mash up of the "LCD Knob" (www.thingiverse.com/thing:51020) by Mrrocketman, with some mods to make it useful on my 6-axis Stewart platform.

My changes:

• add relief under the know for mounting hardware,
• add labelling (using the write.scad library) to identify the axis
• add a set-screw hole to hold the knob onto the shaft
• changed the shaft diameter to 1/4"

Mrrocketman's knob was licensed as Creative Commons - Public Domain Dedication, and so it this one.

The openSCAD display works slowly on this object. I am using a middle-aged Intel i7 machine (3.2 GHz), and it takes 4 seconds to update the display.
