For SquonkModY V1.0 and 12mm ModDog 510s. Will also fit other version of Y_mod including Slimfast, Nutter, etc, except 2x700 (Fatboy) bodies. Order this only if you want to print in STEEL.
WARNING: Take care as the button is always linked to the positive side of the battery and the metal plate/atomizer is negative. Don't keep it in the same pocket as your keys or it might short. Stick some electrical tape to the back of the button and cut round it with a sharp knife. That will isolate the button.
Note: Because of the steel printing process where shrinking of material can exceed 5%, this is offered as a seperate model/product to ensure perfect fit in the Y_mod.
If you are looking for other materials and different sizes, eg 16mm 510, 22mm 510 or MM510, see shop.
