The client wanted a pixel strip in place of the oled on the back, which added complication bc it eats up a lot of space that could otherwise be used for wire management. My biggest gripe is that proffie compatibility is almost an afterthought. Once you glue the board down you need either a super low profile 90° usb cable or do what I did and sand the plastic insulation off of the one you have you also need to trim the little 'tongue' at the back of the npx pcb holder that helps with wire management or there is no way to get the SD card out.
Those are my only real gripes. It's a little unorthodox of a setup but this is a bit of an unorthodox hilt design. I've done wayyy harder. Oh one other thing, you won't really need the four large magnets for the switch box. It's super tough to get off with only the small ones. Also make sure you sand all of the 3d printed greeblies or none of them will go together correctly. Not a huge deal. I got the install done in a weekend working on and off on it.
