Dice

I Printed with an Ender 3 Pro. I would recommend printing with .12 mm layer hight and 100% infill for weight and durability because the dice is so small the .12 layer hight won't take long to print. But .2 mm and 20% infill would also work though it would be less durable and the holes would be harder to see. Scaling the size up should not be a problem but I would add supports if you are making this bigger
