I have done that in the past and most of the time it has worked out ok. I have received stabilized burl in the past though, that even though I made the mod it had many voids that were impossible to fill and the wood was a bit 'mushy'. It might be a good idea to post the link to the wood you were interested in so we could take a look at it b4 it was purchased.
The dimensions I would need that would cover any model would be 2 3/4 x 1 1/2 x 5. For just a 18650 model it would be 2 1/4 x 1 1/4 x 5 inches.
Good to know!
I agree, they do all look amazing!
Hehe
