This Repo contains the .stl files and code needed to make your own 2x3 tile matrix. I've also included a copy of LMCSHD compiled from my fork and the gerber files for the PCB design. Here's a link to my onshape page where you can copy and modify the 3D print files yourself https://cad.onshape.com/documents/0b75d8a92eaed112abe058e4/w/ae56d212076a93f52d54f4f5/e/923ae6ff45cf32c0e0cd9106?renderMode=0&uiState=663526a8ddded813a2aa8592
