I needed to measure a fillet that was somewhere in the 20 to 30 mm range and could find any models so I remixed my favorite set to accommodate my needs. The outer diameter is the same as DatumCAD's so if you're using them (like I am) this one will fit right in.
I did however make the inner diameter smaller to accommodate the larger radii. Also I used 2mm increments for the same reason.
No special print instructions.
Enjoy.
