Any suggestions on a drip cup or something to put over the 510 connector to give the mod a more finished look and protect the wood. Something that will still fit the nimbus.
not sure if it would work .. but what about a copper end cap for copper pipe ? ...

could drill it out just big enough for the 510 connector to fit in it .. and then a little larger for the wood ... and bend the top flat to come out on the wood a little bit ...
