Mouth piece for Dräger Alcotest 7410 Plus

Print both parts with a layer hight of 0.2mm. Infill is not necessarily needed but 2 permiters (0.8mm wall thickness) with a 0.4mm nozzle should be the minimum. No brim or support needed

Before assembly, you MUST place a piece of fine cotton in the middle. This is realy important to protect the Alcotest device from body fluids and fine particles.

(For artistic reasons, shown in the picture is a piece of paper towel instead of cotton)

Remember: for hygienic reasons this is a single use trow away piece, exactly like the original part
