1x 18650 tube style light with >8mm driver compartment height for 2-layer driver.

I have a driver I want to use in an EDC style tube light (like an S6) but it’s pretty tall, I would need the pill to have atleast 8mm for the driver to fit, the main [contact] board is 17mm Ø. I will make due with any size emitter mount but 16mm would be perfect. Anyone have any suggestions? Thanks.
