My biggest problem is finding sources for fabrication.
For example : i need someone to make a threaded aluminum enclosure that has transparent aluminum kinda like what apple is doing on their keyboards and trackpads. you don’t see an opening but yet light shines through.
same thing goes for assembly services, injection molding. The simple stuff any shop can do but as soon as you want something a bit more elegant or fancy . they brakes slam shut.
so where do you find such guys ?
