Prototype built, typing on it now! It took a while to get it built since I've been busy with work and college stuff, but it's finally done. I haven't completely finished making the case yet, my 3d printer broke mid print and I have to get a whole new heatbed. Just the plate will do for now though.
I figured out that the board supports a sort of 'winkeyless' layout, so I decided to go with that and give it a vintage feel and look. So far, I'm really pleased with the results.
With SA, only the right shift key next to the question mark is in the wrong profile. I was originally going to do a long right shift, but I modeled the stabilizer hole in the wrong direction, so I had to go with a split right shift instead. Still, one key in the wrong profile isn't bad at all. With Cherry profile caps, only the key to the left of 'A' would be in the wrong profile.
