The TDPHSK is a 70 key keyboard in a 14x5 grid. It has a split layout with a slight angle to make it more comfortable to use. To make the switches hot swappable there are Kailh sockets put in the 3D printed mid layer of the keyboard.
I've always wanted a keyboard with the ability to hot swap keycaps with my custom layout. This is a proof of concept that uses a 3D printer to make all the necessary parts to house the keyboard, and accomplish my goals! – ianliu88
