a bit dangerous because it has no batt wrap but you designed it to complete the connection by 510 contact and ss tube. you can make it longer used two ss tubes and drill a firing switch to connect the two tubes while having a threaded batt cap below. that would also complete the connection but still awesome use of epoxy resin
wszystko ładnie pięknie super pomysł tylko mam jedną uwagę jeżeli zastosowałeś rurkę stalową a nie mosiężna to masz całkiem spore spadki dobrze ci radze też o przylutowanie jej do konektora a nie sklejenie bo to ci długo nie podziała
Really unsecure mod. Need at least a vent hole. And the batery is holded too hard, in case of short, you will not be able to remove it fast enought. Hope for the heat not loose the spring and cause a short. Notheless, is a very cleaver desing. Not a dailly mod, but congrats!
