I’ve been using tape for my smaller 18650 to reduce the rattle, but with 16340 it would be a lot of tape. I suppose I could try a few other things but looking for a simple and reusable method.
I was cleaning out the junk drawer in my kitchen today and found my wifes’ baking glitter/sprinkles. They were stored in tubes that looked to me like an 18650, out comes the calipers.
They measured 19.4 outside diameter and 16.5mm inside diameter and 70mm long. I believe she got them from the dollar store and theres more then one.
So I’ll be sanding the outside a bit and will have to use a small bit of tape but it should work. Hardest part is going to be cutting bottom off without crackin the tube. Hack saw really slow should work.
If it works well ill take pics and make a photobucket account to post them. Just thought I would share.
