Drew this up after seeing 507 Mechanical Movements #135 and thought it would be a great way to demonstrate what a reuleaux triangle is. You need to print 1 of everything except for the arm clamps which you need two of. This snaps/friction locks into place, no glue is required.
The wheel titled 'Wheel (As Seen In Mechanical Movements #135)' behaves as it would in this animation, http://507movements.com/mm_135.html, on the other hand the wheel titled 'Wheel' behaves as a normal scotch yoke would.
This is similar to a previous project of mine which was a typical scotch yoke which in my experience spins more freely than this you can find it here:
