iStick Pico dust plug

thingiverse

This plug fits in the mouthpiece of an iStick Pico e-cigarette and stops dust and pocket fluff from collecting and clogging up the mouthpiece when it comes into contact with sticky vaping e-liquid. And in its bright orange appearance, you also prevent people from mistaking your e-cigarette for a real gun ;) Update 24 aug: I uploaded a new version of the model with stronger legs that don't break as easily.
