H2D Gridfinity Build Plate Holder

I needed a possibility to store my build plates horizontally as there wasn't enough vertical space. So i decided to go with the awesome gridfinity as base and designed this simple yet useful build plate holder. It uses a width of 9 columns (7 free columns inbetween). The bottom slot is for the H2D laser plate, the second one for the cutting mat. The other slots are for various kinds of build plates available.
