I made a prospective case for the Dom<-(I got it right this time) tenkey pad.
The built in standoffs will use 3/8" 4-40 screws. There is a 5mm thick space below the plane where the PCB will sit so soldering doesn't touch the metal. There is a 13mm space for the PCB (final will probably be 1.6mm thick), plate, and switches. The interior has 0.5 mm clearance on each side so there is wiggle room for caps. The outer edges have a chamfer, the while everything else uses fillet. The case is 180 degree, aka flat. There are 4-40 screw holes on the bottom so you can mount feet of your choosing on them. I plan on making 11 degree angled risers to accompany this case which may be attached with 1/2" 4-40 screws. There is one slot for the micro USB output, and 3 slots for USB input.
I have no idea what it will cost to produce this yet, I just wanted to have something ready to get quotes with.
Also, done today. To accommodate requests for Monterey Alps support, I have made a pad which supports both SKCM Alps as well as the SMK pins.
This option means that you can use SMK switches with the PCB, but NOT the default plate. However, I expect I will offer plates with the correct 14mm^2 cutouts with this deal as well (don't tell the Cherry fanboys). Input is requested for what layouts you will be using. Due to the design of the tenkey with the USB hub, I probably won't be offering the SMK compatible Dom. The hub chips and glue electronics take up a lot of board real estate. I haven't designed Rosa yet, but I expect that there will be plenty of room to handle this update.
