I needed some blank panels for my large-ish eurorack cabinet, and while they seemed like the perfect thing to 3D print I wasn't happy with any of the designs I found, so I designed my own. Included are several variations in sizes, and the basic 8hp panel FreeCad file so you can modify these to suit your needs. Note that for the 1U blanks IJ stands for intellijel format, and PL stands for Pulplogic format.
