Tetris fridge magnets

I made some Tetris style fridge magnets. There are probably many like it, but these are mine :)

The are holes are 8mm x 3mm. My printer makes holes a tiny bit smaller than designes, so some 8x3mm magnets fits snugly without the need for glue. I bought mine here:

.. but any same size magnet would probably do. I'm printing these in different colors to make a set.
