3d Printed 510 Cartridge Holder-Textured Terracotta Edition. 
This item is printed with a Matte Terracotta colored filament to mimic the course texture of terracotta gardening pots. 

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.
 
Item measurements are below:
52mm wide x 48mm tall 
Each of the 4 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.
