420 Toobie (Doob Toob)

thingiverse

This is a fancy "Doob Toob" for "smoking" enthusiasts. Simply load the bottom chamber with dryer sheets, and screw it to the tube. Exhale smoke through the tube in order to mask the smell of your "activities". Replace the dryer sheets as necessary or fill it with your own favorite smelling objects. This design was my first prototype. Please check out my second version here: https://www.thingiverse.com/thing:2870280
