I made one 510 bottom feeder which run's on one 18650 or two 16340's, I prefer the IMR, The feed system is a 20g needle the wood is redoak and the horn stytle switch.
then I made a VV dual 18650 with digital read out, I found the case on ebay, durable heavy plastic, plenty of room in the box for the display / switch/ and regulator pcb board. this is a 808-901 connection.
and last butr not least, My tekkeon p18 in a redoak case , all connection's make contact through the holes I made, The only issue I could not find an alternative master on off switch for the tekk so till then I have to open the case to turn it on . even all that it is still not a big deal

hope you enjoyed my show, I will be adding more as they dry
almost forgot to mention my bottom feeder hold's 6ml
