I'm trying to find tiny U-channel. I need the inside opening to be ~1.6 mm to accept a typical PCB. The sides must be tall enough to grip and hold the PCB, bun not obscure significant parts of it, so no more than 1 mm. The wall thickness - does not matter that much, I imagine that being rolled from sheet metal. Material is probably going to be steel given the requirements, but any metal would do.
Ability to get in bulk is great, but I'm fine with ripping it out of something cheap for the prototype. I only need a few inches.
The closest I could think of is hardware on umbrellas. But it is not easy to find, since Amazon pictures don't show the hardware close enough and local stores don't tend to carry umbrellas in California
I want to make a low profile PCB holder/vice of sorts, but I need the actual holders to be as non-intrusive as possible.
It probably does not need to be U-channel, it probably can be just an angle. But I'm not sure an angle this tiny would be structurally sound.
Ideas are welcome.
