Blowgun mouthpiece and darts.

thingiverse

Fits a 20mm (or 19.5mm Alfer) aluminium tube sold at home improvement stores. This comes to a cal. 650. You may have to adjust the scale if you are using another size tube. Prints without supports. 15% grid infill worked for me. Don't shoot at animals, or I will come for ya! Instructions Print the parts upside down from shown, no supports needed. For the darts you may use a brim if they won't stick. Use a bright color for the darts ;-) Get a piece of aluminium tubing. I used 19.5x1.5mm. Length should not exceed 120cm. De-burr the tube at both ends, inside and outside. Attach the mouthpiece with some epoxy glue. The Darts are hollow, so they can be filled with water for more weight - and a little trail. Ready to go!
