(fiber laser) Rotary tool ring add-on

cults3d

I have a rotary tools with my fiber laser. Once in a while i want to engrave rings. Rotary's are expensive and i do not need it enough to buy a new one only for this purpose. This add-on can be used in combination with the existing rotary. Just print it and put it together using a M8 bolt and nut. Without the ring holder the ring can be clamped on the outside. With ring holder ring can be hold from the inside.
