UPDATE: Version with improved hinges: https://www.thingiverse.com/thing:3510716 Hinged triangle-square dissection (Dudeney's dissection) is now a reality. Using an X-acto knife, I carefully cleaned away stray filament from near the hinges before attempting to bend them. I previously tried printing this model https://www.thingiverse.com/thing:263152, but unfortunately, the hinges did not print successfully with my printer. This led me to design my own version of the hinges. The geometry for the dissection comes from a reliable source: http://www.gavin-theobald.uk/HTML/Triangle.html My idea for the hinge was inspired by this instructable: https://www.instructables.com/id/Perfect-3d-Printed-Hinge
