I made these for my 2011 Triumph Speed Triple. They are pre-scaled up 4% from my original measurements to provide a press-on fit with ABS. They should work on any 8mm head, but may need scaling with different bolts or materials.

I printed 2 sets of 30, or enough to cover all of the bolts on my Triumph, and it took about 90 minutes per set @30mm/sec.
