18650 Battery Spacer 23mm Outer Diameter

thingiverse

I designed and made this so that I could use an 18650 battery in my "as seen on tv" type flashlight that uses a three AAA battery pack for power. I made it so that it is not a full sleeve, and it uses a lot less filament than a full spacer. In my particular flashlight it keeps the battery snug enough that it doesn't move around inside, but I haven't had to worry about it getting stuck in the flashlight body either. Oh, it is made so no supports are needed. I added a circular base for stability. Print with this base flat on the bed. It very easily snaps off when the print is finished! Do the battery swap at your own risk! I am not responsible for how this is used. Do your research on this! Thank you! Daniel
