mylk [mech] Box Mod




Duel 18650 Mechanical Mod with "Fat Daddy Vapes" 510 connector, chemical etched skulls design and (neodymium) magnetic battery cover closure. 


Made this for my brother as a Christmas present using all the techniques I have learned making guitar pedals and mini amps. Made from a standard Hammond 1509b guitar pedal enclosure etched with a combination of Ferric Chloride, copper and Citric acid.
