Update 1: Slightly longer slots for 18650 batteries to remove them easier.
Update 2: Increased diameter for the 42mm bottle holders.
Update 3: Added files for a print with a seamless top (needs to be stopped before the last Millimeter to assemble and include the charger. Easiest way is to insert a filament change before layer 240 (on a 0.1 resolution) or layer 120 (on a 0.2 resolution)

This Holder was designed to hold up to four 22mm E-Cigarette tubes or Vaporizers, up to two liquid bottles with a diameter up to 23mm (e.g. Unicorn Bottle 30ml), up to two liquid bottles with a diameter up to 42mm (e.g. Chubby Gorilla 120ml) and up to three 18650 batteries. The middle battery slot contains a charger (use a disassembled Efest SLIM K1 Charger for the electronics. Use a sharp nipper or a knife to break the lower part of the original charger from the upper part at the weld).

Assembly tip:
After printing both parts, remove the moving plus connector from the disassembled charger by releasing it from the spring. You need to move the upper part of it through the slot of the charger part, then connect it to the spring again. The charger must be placed in the holder with the front part first and the firmly pressed in place until it's surface is even to the surface of the holder part.
