Tetris ice tray
thingiverse
I'm really keen on printing it at 100% scale, that way water won't seep into the model itself. Tip: if you're having a hard time getting the ice to budge, just run some lukewarm water under it for a few seconds and then tip the ice out. This design was created with Tinkercad.
