I know Moxi has some stuff on buttons in the Parts Archive forum (DIY illuminated buton, Datawheel for the MIDIbox Community). I’ve got a thread on fiberglass (I think in the Tips and Tricks forum). There are also box(es?) in the gallery using similar designs. I need to start doing smaller stuff like Moxi’s. It makes more sense to make caps to fit a cheap acquired part than to try to find them.
Duplicating the switch/fader shafts for the female molding is the main part that frightens me.
I really like the fiberglass. I’m figuring it also has potential for making extensions or mods to existing plastic bodies.
