If they're the ones I think they are, they do make really good 18500 battery holders, they don't
vape well off the 3aaa batts though.
I have made one (link), but I don't like drilling them, so my button's on top, I've been looking for a couple more to mod, but the one's I had I got for a buck each, now I can't find them for <$4ea (maybe $3.50ea in a 3 pack)... If I can find one for a buck I might put the button on the side this time, since I found my drill now, before I was making my holes with a razor, and it can't cut aluminum, I would probably want to put a bi-color power indicator led (red for master power, green for momentary switch)... If you PM me for a parts list, I would be glad to do the labor free, if you send all the parts and a SASE for return shipping (sending money for the parts comes too close to 'selling' the mod, I think), or if you want me to teach you to fish, I can help there too...
