BCD (Bolt Circle Diameter) : 122 mm
It has the same size than a normal sprocket (3 mm deep) and has five 10 mm holes with 12 x 1 mm counterbore. See picture for the other dimensions.
I printed this sprocket guard to fit on my vintage roadbike. I removed the 52 teeth sprocket which I rarely use in the city. I replaced it with this sprocket guard to prevent damaging my shoes, pants or laces.
Printed on my ender 3 v2 in PLA + (100% infill)
