3D model description

This is a straw holder for an MQ-3 alcohol sensor. The MQ-3 is used by the DrinkShield (http://www.gfxhax.com/drinkshield/). The DrinkShield is an open source breathalyzer kit. One thing that happens when people get drunk is they tend to put their lips on the MQ-3 sensor which is a bit hot. This add-on allows you to blow into the sensor without having to worry plus has the additional benefit of holding an optional straw at the end.

This will work with any MQ-3 but you may have to adjust for different straw sizes.

3D printing settings

Simply print on a makerbot. The original source files is done in OpenScad but the STL is available as well. Take a straw (I use ones for Malts/Shakes) and cut a few small lengths. Those should fit in the end of the holder. If you don't care about germs you can just blow directly into the holder itself.

Remember, drink responsibly ;)
