Not sure how to feel about it? Let a roll of the dice decide.
Maybe you're happy. Maybe you're sad. Or surprised, or grumpy or just a bit saucy. These emoticon dice give you the feels.
Designed in OpenScad, starting from Marius Kintel's LetterBlock.scad file.
You will need to scale the print down in your printing software, unless you want a giant die. 16mm is the most common size for game dice, and works well for this print.
I printed from Cura 15.04 with the following parameters:
Layer height 0.2mm,
Shell thickness: .8mm
Fill Bottom/Top thickness: 0.8mm
Fill Density: 100% (use 15% to test how it comes out first, but you want 100% for the weight)
