Am I The only one who thinks there's no good reason why the Behringer CAT synthesizer shouldn't have cat-shaped knobs?!

I made these ones, and now it looks even more pretty (and it still purrs beautifully, of course). :)

Print the knob and cap parts in different colors, it looks better (white and black are the obvious choice, but do as you please), then glue the cap on the top of the knob. WARNING : don't glue the knob to the potentiometer axis, because you might want to put it back later the way it used to be (well… who might want that, right? but you never know…)!

Also, I made STL files with a bunch of 6 for each part. It saves time, and it prints better as the printed matter has more time to cool down.

PS : this works well on my CAT, but remember the printed knobs should easily fit on the potentiometers' axis. Inside diameter of the printed part might vary depending on print temperature, plastic retractation, etc. Make tests, and don't force it to fit, so you won't risk damaging your precious synth, alright?
