Created to hold my vape vertical to help with clogging, designed it around a honeystick vape battery that holds a 510 thread vape cart that measures 11.2mm on my calipers, you may need to adjust based on your battery, but it is fairly forgiving.

I used a spare o-ring but I imagine a small elastic band, or hair tie or something would work.

easy to remix and add logo or text if you like, I have the larger one in the pictures printed with fuzzy skin.
