Dual Tube 18mm Adapter (Arizer Extreme Q)

thingiverse

This adapter should NOT be used on the vaporizer end but rather on the other end in an 18mm female joint water filter where the adapter won't heat up enough to have you inhale any of the plastic. You can also use the small tube cuttings provided with the Extreme Q to connect two balloons to this or just one but with a carb hole. Printing without support, I used 0.06 with PLA+ @215/60°C on the Ender 3 Pro. Both ends have an outer ⌀ of 10mm (and inner ⌀ of 7.6mm), fitting the original 8mm ID silicone tube quite snugly. Almost all of the adapter is 1.2mm thick except where reinforced. The only downside is that you have to get rid of all the stringy filament inside before you use it, but how much probably depends on how you slice it.
