Blowgun Mouthpiece (parametric)

I programmed this mouthpiece inspired by a mouthpiece I have. The big difference is: it is oval, not round.

To complete your blowgun, you need a tube. I use aluminium tube with 10mm diameter (1mm wall). you get those in every hardware store. To comply with the official competition rules for Gemany, the maximum length of the tube is 120 cm (not including the mouthpiece.

With the  OpenSCAD modell, you can adopt the mouthpiece to your needs e.g. bigger tubes. The parameters for the mouth side fit me quite good, but they are also changeable.

For the tube diameter, I had to add 0.1mm to fit the mouthpiece over the tube.

BTW: in Germany, blowguns are not considered to be weapons, they are classified as ‘toys’. But be careful: those darts can't kill you, but they can cause hefty injuries.

Have fun.
