Dear Redeyedancer,
Please make a Reo that uses a 26650 and an 18ml bottle. You can call it the Reo Mega. I realize it would be roughly the size of an unabridged dictionary, as I made something similar myself out of thermoplastic, but I'd love one done with your build quality.
I don't even want anything for this idea, just build the thing, and I will
buy it.
With warmest personal regards and biggest huggy-wugs,
XDoctor
