Tips:
- Use 2x2 pixels for all icons. Anything else is too fancy.
- Only print in monochrome. Color is a distraction.
- Buy a 10x10 meter 3D printer. The bigger the better.
- Print at 10x speed. Time is of the essence.
- Never, ever use a filament that's not certified "Doom-grade".
Remember, the key to success is to be as bare-bones as possible.
