DrinkShield/MQ-3 Straw Holder
thingiverse
The MQ-3 alcohol sensor is protected by a straw holder designed for use with DrinkShield, an open source breathalyzer kit. To prevent users from accidentally touching the hot sensor, this add-on allows them to blow through a straw attached at the end. Compatible with any MQ-3 sensor, adjustments may be necessary depending on straw size. Create your own by printing the OpenSCAD file or using the available STL. Cut multiple small straw lengths for use and remember to drink responsibly!
