I know, but where do I find a plastic tube with this dimensions?
PVC-Plastic tube for electric wiring is normaly 16 or 20 mm outside diameter.

Mine came from other 3xAAA lights , Saik SA-8 's I think . [ I have 2 ]
You could just make one out of some wide bodied tape .. Cut some of the roll , wrap around a 18650 back to font , [ sticky side away from the battery ] dont wrap tight ..
Then just build it up until it fits the light ... [ Tape the right way after first layer - sticky side in ] And you have a battery spacer .
