Your incredible, "A Tribute to NiteCore D10" is the reason I decided to get one. And for that, I thank you.
As has been warned by many on this group, I find myself "needing" more LED flashlights and associated items.
To that end, could you kindly tell me where I could buy the holster with spare battery compartment; as found near the end of your tribute - 8] Holsters? https://www.candlepowerforums.com/threads/255627
