I just took his python script and hacked together a quick and dirty 3x3 panel for each of the 3 files. This can be ordered using 10cm x 10cm panel services ;)
DO NOT RUN THIS using python2, use python3 instead!
NOTE: I ordered the panels on elecrow, i am still waiting for them to arrive. So right now this script is untested, use at your own risk!
