This is a quick Dice MX Keycap that I modeled up for an electronic dice project I am currently working on. Thought I would share.

I recommend printing this at a fine layer height. A brim is built into the STL model to help with bed adhesion.

I used a Sharpie to add the black to the model. I dont necessarily recommend this method due to the bleeding issue. Paint would likely work better.

Enjoy!
