I've been tinkering on this for a couple months in my free time. It is basically a 40% layout with a 10 key.
90% of the time I use the 10 key on the side of my keyboard when I model or use my calculator etc. I wanted to try a smaller keyboard on for size, but I didn't want to give up a 10 key. I also wanted to get a better feel for switch spacing and layout.
I modeled my plate in Fusion 360.

I printed the plate in my flash forge 3d printer. I only have a 6"x9" bed so I had to break the switch plate up into 2 pieces.

I used 1/8" square trim to attach the plate pieces to. The plate is 5mm thick and feels rigid. I'm hoping I wont have to brace it in the middle.

Next I dry fit my switches (Browns) with some caps to make sure my spacing was good and my caps would going to clear.

My intention is to epoxy the switches in place. They are snug when I push them in, but I'm afraid they will pull loose if I need to pull a keycap.
I ordered wire to wire the switches. I have a teensy2.0 on a breadboard to test it on. Once I'm satisfied I have the software working I'll hardwire it to it's own teensy. I haven't settled on 3d printing the case or it or just making it out of wood. I'm currently waiting for my mass drop order for Granite keycaps to show up. Once I get a good look at them and get a feel for how they look I'll decide.
I'm also trying to figure out where to source the stabilizers for my space bar. (Looking for a good place to order from). In hindsight I might have considered just putting extra cherry switches on either side.
Comments and suggestions welcome. This is my first ground up build. So far I'm happy with where I'm at.
