3D Printed Battery Adapters

Nice!

Wow!

Those are pretty cool.

THAT is a very cool idea.

Thanks everyone!

I like C and D cell lights but I don’t like using alkalines and I like to have lights that can run on different “fuels”. The 3D printed adapters came out pretty nice, which is why I an offering them here.

Since Mag-Lite uses very chunky springs for the tail, I’d prefer the 18650 be in the middle of the adapter in this case, if possible. Could you make one that way? [Note: I’m not ready to buy right now, so don’t do it just for me.]

That’s kinda what I did for the D cell lights by using two adapters, one to change D cell to C cell and the other a C cell to 18650. There is a washer on the base of the D cell to C cell adapters that mates with unmodified Mag D cell springs so that there is no need for a spring mod.

I find that the smaller springs on C cell Mags work fine with 18650’s and even smaller cells.

I am working on a 21700 to 2C adapter. 21700’s maybe the ultimate “fuel” for a 2C light in terms of run time - I don’t know of anything with more Watt hours that will fit in a unmodified 2C tube.

Have you tried printing a 3C to 2x 18650 adapter for Defiant 3C light? The two 18650 cells would be connected in parallel to extend run-time. My Defiant 3C eats through a single NCR18650B cell very quickly.

I haven’t done a 2 18650 cell adapter as of yet, with 2 protected cells there is only about 10 mm left to work with to fit everything in.

I have sold most of these elsewhere and only have a few adapters left. Due to lack of access to a 3D printer during virus shut down, I will not be printing more for a while.

One of the last ones I completed is a 26650 to 3D cell adapter:

No
6D to 2x18650 adaptor?
Just kidding

xxo · 2020-08-05T23:09:02.000Z

If I ever get a 6D ML300, I might come up with something to run a couple 26650 specifically for a 6D but 2 of the 3D to 26650 adapters would work just as well.

xxo · 2020-09-19T00:46:03.000Z

I am starting to print some of these again on a limited basis.

OOoooh - Aaaah ! Yeah !

I was wondering what to do with my 3D Printer .
One of these days I will have to print a flashlight .

WOW! This is super cool! I have one of these with the original color interchangeable lenses in the tail cap. Awesome cell adaptor!

Some of my first attempts at 3D printed adapters were intended for the old Fulton moonbeam running a Nite Ize LED drop-in.

xxo · 2020-10-06T23:26:15.000Z

I am thinking of making some adapters for moding incan 3 D cell Mags that would run them on two protected 26650’s without any need to do a spring mod. Does anyone here still mod Mags? I am trying to gage interest.

Thanks.
