So i’ve been wanting to do this for a bit. FR4 plates. FR4 is a composite material composed of woven fiberglass cloth with an epoxy resin binder that is flame resistant (thanks Wikipedia). Basically, it’s the substrate found in most-to-all PCBs.
It’s properties put it pretty much in between polycarbonate and aluminum for plates. It’s flexy and will give, but still provides support.
I have some prototype Jane V2 plates without copper on them. This is how I plan to do other plates.

The prototype’s cutouts are great. I know people have had some issues doing good cut outs before, but I got my fab on top of it. Alps plates will be 1.2mm per spec.
The colors are based on the solder mask provided by the manufacturer. I’m planning on matte black, blue and red at least - maybe white or green too as limited numbers. ISO-only plates will probably only be offered in one or two colors max, as there’s generally less demand for them.
I might mess with the relief cuts and stuff, not too sure if they’ll really change anything since the thing is pretty flexy as it is.
These are pretty easy to stock, so I will probably just direct stock them given some interest.
Plans for now:

  • TGR Jane V2 - MX ANSI, MX ISO (limited colors), Alps (probably basic ANSI tsangan or 6.25-space, with a fixed bottom row)
  • TGR Jane V1/Orion/Mech27/Mira/Moon, same options as above - anyone else know what other boards are compatible here? I know there’s a few.
  • Google Form for layouts, colors, and keyboard suggestions:* https://goo.gl/forms/DOpcuvRLuS9JNG2q1
