I found this design on printabrick.org and decided to redraw it so that I could make it larger. However, I don't think it's based on a real Lego brick. Please correct me if I'm wrong, but I couldn't find it.

Anyway, it makes a perfect little desktop trash bin. I printed mine at 450%, which is the max area available on my Prusa MK2.5s.

Enjoy!
