    Default DIY Rubber Knobs for Controllers

    I've been working on a couple of custom MIDI controllers for use with Traktor DJ. I built a hardware "platform" (https://github.com/elysion/encoder) that has PCB designs and software that help to get speed up the development of controllers that have pots, encoders, buttons, sliders, leds etc. After building the first devices I realized that it is fairly difficult / expensive to source knobs, that have a rubber coating, at least here in Finland. The Chroma Caps sold here on DJ Techtools look really nice, but cost quite a few $$$ after you add shipping and taxes. Thus I decided to try and create the knobs myself!

    I designed a d-shaft knob with Fusion 360 (https://a360.co/3bJeQV5) and printed a couple of them on my Anycubic Photon S. After rinsing and curing the knobs I poured on top some rubber paint used for "dipping" cars (I used a local brand Maston RUBBERcomp, which I guess is similar to this: https://amzn.to/2vU4lPd).

    The knobs turned out pretty nice (and thus the post here on the forum). Here are some pics of the knobs:

    Sum up: If you are able to buy Chroma Caps and they fit your needs, buy those. If not, creating your own custom knobs might work.

    Thanks! Forgot to mention that this might also be useful if you need to replace a cap in an old / rare controller where spares are difficult to get / expensive.
