Crulius is a tool for drawing smooth rounded edges on 90° corners.
Unlike a standard radius ruler, Crulius extends the ends to a straight line, making it easier to align with a straight edge and add a curve with a specific radius to create a rounded corner.
It comes in two sizes:
- 1 to 12mm radius in 1mm increments
- 2 to 24mm radius in 2mm increments
Printing tip:
Change the filament after reaching a 0.6mm z-height to make the font stand out.
What does Crulius mean?
The name combines “corner”, "ruler" and "radius," with a playful twist on the crude sound and a hint of a Roman touch.
