This is a pie made up of 3 parts: a base with the Unit Circle, the filling that spins with a 1-radian opening, and the crust with 100 digits of pie, that screws onto the base to keep the filling in place. The crust and filling are textured but have smooth options available.

I only printed the crust with supports, although you may want supports on the threads of the base. All models fit on an Ender 3 and should fit on most standard-sized printers.

Everything was made in Fusion 360 except for the unit circle values and radians, which were added using Tinkercad.

Happy Pi Day!
