3d Printed 510 Cartridge and Battery Pen Holder.
Makes storing cartridges much easier and keeps them in an upright position to ensure the heating element of the cartridge stays saturated in the cartridge oil. This print has triple wall support and is a very sturdy plastic object. Empty cartridge not included.
 
Each of the 25 holding spaces are 12mm wide so they can accommodate most vape pen batteries of a small or medium size in addition to 510 Cartridges. They also hold the Arizer Extreme Q mouth pieces nicely.
