bUbble shOOtter

Thanks to the great 3d scanner design from Ferreti, I've adapted to a bubble maker, which uses 2 stepper motors each one with 6 pallets for making bubbles, and 1 usb fan for making the air flow.

Hints
Best way to make liquid composition is to use
- 6 parts water
- 2 parts dish soap
- 1 part sugar or glycerine
and slowly mix it without making bubbles.

The parts where liquid stay is about 160 ml volume so, based on above hint, I've put 125 ml water + 25 ml dish soap + 1 sugar teaspoon.

Bubble support may not fit perfectly in stepper motor so in my case I've used a lighter to warm a little bit the head of the piece.
