The STL is designed as a USA size 7 ring, 17.5mm inner diameter.  Resizing can be done in 3D Builder, Meshmixer, or Rayware Desktop.

The v100 STL is pictured.  v105 STL has the official Bolt Speed font used by Sprintray, and 5% vertical stretch to improve roundness.

A custom VuBase support is designed into both files.

This is designed for printing on Sprintray Pro printers.  Print, wash and post cure as usual for the resin of your choice.  OnX bleach pictured here on Pro 55s.   It should print on other resin printers but has not been tested.
 

Painting (optional): Black spray primer, metallic silver spray paint, oil based sharpies.
