3d printed cartridge holder for one 510 vape pen and up to four 510 cartridges.
Battery/empty cartridge not included.
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.
 
Item measurements are below:
60mm long x 60mm wide x 29mm tall
(The four lower spaces are 18mm tall) 
 
Each of the 5 holding spaces are 13mm 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.
