Been there with the glued in adapter. Did that on an ego batt once. Hopefully you have a bit of thread left to grab the adapter. I used just a drop of epoxy on each side of the threads on a 510 to ego adapter and it's still together and getting usage. That's been about three months so far. Now that I made it public it will probably fall off tomorrow.
lol hope it don't. Someone else also said to use 5 minute epoxy. If I knew which box my crystal effects was in (crafting thick, dimensional kinda glue) I could probably use that. Yeah, it'll barely seat for just a second til ya turn it some more, so I think I can get it on there, make sure it's working and glue it down. Since the adapter has airholes itself, that shouldn't matter if I cover the ones in the gripper threads.
