Knurled Amp Knobs

I needed knobs of various sizes to replace the ones on my aging amplifiers. So, I created these. This file includes 4 different size combinations to fit different potentiometer stems--both amp style (4.4mm diameter), and standard (5.6mm diameter) which I've seen more on instruments than amps, and finally a micro notched one that I needed (3mm diameter)

It took a lot of trial and error to get them to fit snugly enough and to print well. These work for me! See the pictures!
