A very simple print of the “hat” aperiodic monotile recently published by:

David Smith, Joseph Samuel Myers, Craig S. Kaplan  and Chaim Goodman-Strauss.

The model is approx 30x30mm and 2mm thick.  The gcode contains 16 instances in case you want to just print out a bunch and play around with the tiling.
