Always wear safety glasses!!!!

This blowgun is made from 3 bic pen tubes, 1 mouthpiece and 2 couplings.

To make This:
Step 1 = Print 1 ea. Mouthpiece.STL , print 2 ea. Coupling.STL
Step 2 = Remove everything from 3 bic pens, leaving the tubes only.
Step 3 = Press 1 pen tube into the mouthpiece until it stops.
Step 4 = Opposite of the mouthpiece, press 1 coupling 1/2 way onto the pen tube.
Step 5 = Press a second pen tube into the other 1/2 of that coupling.
Step 6 = Add another coupling to the end, then add the last pen into that coupling.

The mouthpiece was designed with a 5mm blowhole to prevent the intended 6mm airsoft bb's from being sucked into the shooters mouth. Always only blow into the mouthpiece, do not ever suck. It's not recommended to scale or resize this design.

To load the blowgun: Drop 1, 6mm airsoft bb into the end of the tube. The bb should fall all the way down the tube toward the mouthpiece. When loaded the blowgun can be pointed downward about 30 degrees because of where the bb sits while waiting to be shot. This was designed into the mouthpiece to prevent the user from inhaling through the tube in order to keep a bb from falling out. Remember to be safe!

While wearing safety glasses
Never shoot toward any person / people / or animals.
