WARNING- Combining into staff may require additional effort and materials after printing. I modeled this to make the option possible however not a primary function. I am not able to print this at this time and do not guaranteed it will have the structural integrity to handle being combined into...
Took about 4 hours to complete, ran into some hickups. It would be months before I can test print so I'm gonna go ahead and release it now. Theoretically it ca can be combined into a staff if you inbed 6mm wide or less magnets into the back of the handle.
Cavity is large enough to accommodate up to 8 chain links.
Not my best renders, but it'll do.
