Ooh they sure would. It was a “proof of concept” like all my projects, but I rarely go back and improve them if they’re good enough. But wooden knobs would be a definite improvement

Listening now. I ended up using conditioner I had, and I’ll continue to use it on the exterior for appearance, but I’ll leave the interior parts bare from here on out.

That’s a pro tip I never expected. I’ll pick some up when I get toothpaste

After using it once, I would also like a single knob. Every project I do is a “proof of concept” that I never go back and improve on. But I’m getting a 3d printer, maybe I’ll print some gears.
