Art Deco Knobs for 6mm 1/4inch rotary encoders

These are a few knobs I ended up making for my DecoTime timer. They are currently sized for a keyed rotary encoder or variable resistor. The holes are 6mm (1/4 inch), and keyed to 4.5mm, a common standard size. I made them a tight fit, so you may want to scale them up a bit, or be ready to sand them down a bit.

A few are art deco designs to go with my art deco timer DecoTime (http://coolate.com/blog/coolate-pages/deco-time-angular-timer/).

They might make a good starting point for others.
