A hexagonal ice tray for your summer ice-teas
Prints perfectly without supports.
It would be great to see how it prints with flexible filament.
I tried it in ABS and sadly in order for it to be watertight, the wall thickness has to be just beyond what one can call flexible, thereby making it harder to remove the ice once hardened.
Tip: if you're having trouble with the ice not wanting to budge, just run a little lukewarm water under it for a few seconds and then tip the ice out of the hexagons ;)
