Heptagon-square dissection puzzle

This is a puzzle version of the seven-piece dissection of a heptagon into a square by Gavin Theobald. The model comes with a two-sided display plate that has a heptagon frame on one side, and a square frame on the other. The square frame is printed separately, and slots into a groove on the bottom of the base plate. It is printed with no tolerance, but mine fit in just fine: just press on each of the corners in turn until it can't go in any further. For greatest economy, print the seven puzzle pieces by object. In the .3mf they are pre-arranged with enough space between them; the STL models will require separation. Also, in the .3mf there is no prime tower – I had no issues, but you may want to alter the purge settings or include a sacrificial cube.
