This is a 30 mm cube perforated with initials on three sides. I wrote a Python script that automatically generates these personalized cubes with any initials — this STL is just a demo example with X-Y-Z.
✅ Great as a desk trinket, small gift, or keychain add-on
✅ Slices easily, prints without supports
✅ Works best at 30 mm, but can be scaled up or down

This file is a sample. 
i also made an html version that you can use to make your own cube.

Enjoy, and I’d love to see any prints if you try it
