A light dimmer knob remixed from the Basic Trilobite. We're a big Girl Genius fan family so this was a fantastic addition to the household.
My primary site is Youmagine, I'm posting here as well as a courtesy to the original creator.
The settings for the shaft diameter make it a nice snug press fit on my dimmer shaft with my printer, but you may have to play with it. The SCAD is there.
I printed in gold PLA then used Spanish Coffee Rub-N-Buff on it to give it a nice finish.
I had to run the original Trilobite STL through Netfabb, it was kind of a mess and was blowing up my software. The fixed STL is included here, it's down from 27 to 4 megs for the same object and loads cleanly now.
I normally release my stuff Public Domain, but I'm restricted from doing so because the source for the Trilobite is CC-non-commercial. Sorry. Talk to the originator of the original design if you want to sell these.
