Pythagoras's Theorem Magnet

Things you need to turn this into a Fridge Magnet:

2-4 Neodymium Magnets depends how strong you want it to stick (6x3mm)

Superglue to glue the magnets in the holes

The printed 3D Model I created

After Printing just glue the magnets into the holes on the back of the model.

I recommend using the Ironing Print Setting for a smoother finish.
