Not exactly a flashlight mod – But I think this is the best place to ask this question.
I have a few electric screwdrivers that run on Sub-C NiCd batteries.
Over the years the packs have failed. The replacement OEM packs are too expensive and the clone packs fail fairly quickly.
Or the chargers have decided to quit.
Sooo, I got hold of some 18650 holders and cobbled together the holders you see here.
The voltages are close enough to run the motors as long as I use a cell that can put out a few amps.

What I’d like is something more elegant. There is about 26mm of space diameter wise down the tubes.
Something that could hold a 21700 in a screw top tube would be very nice.
I guess I’m basically looking for thin flashlight body with no electronics that I could hook to the internal connections.
Would a few of you measure the OD of some 21700 tubes for me? - Just to see if they would fit.
Someone with a 3D printer could, I think, make some money marketing an adapter for these things.
I’d do it, but I’d need a 3D printer, the software, someone with the skills to run all of the above.
Any ideas would be welcome.
All the Best,
Jeff
