Duck Call with Reed

thingiverse

Assembly Video Decibel Test Video This is a duck call me and my students worked on to learn about 3D printing and modeling. It works great. We did have to sand it a little to get it to fit smoothly in the tube. Also the reed should be sanded fairly smooth. Print took 2.5 hours at .2mm medium fill on XYZ printer. You might have to slightly bend the reed away from the sounding board to get it to make a sound. Also try blowing very lightly at first and adjusting the reeds position. I've include a slightly thicker reed if you are having issues printing the normal one. The thicker reed requires more air to make a sound but as such can produce a louder sound. One thing I'd like to do is print the stopper in a flexible material. Sadly our printer will not do that. If you print one please share. My students would love the feed back! I'll update soon with a video with the duck sound it makes. We've decided to submit this to the #MakeItLoud competition on the off chance we win a printer (then we can print with flexible material). Current call is about 84db according to Sound Meter app on Android (see second video). Print Settings Printer: XYZ Rafts: No Supports: No Resolution: .2mm Infill: Medium or High Notes: I printed mine at .2mm with a medium infill. I printed some with very little infill and the (stopper and sounding board) broke eventually when I taking it apart testing different things. ABS with a heated bed. Post-Printing Construction DB Test 1. Sanding Be sure to sand the reed (or use your own duck call reed) and the sound board where the reed touches. Your printer might print it fine with out a need to sand. The easiest way we found to sand the inside of the tube was to wrap sandpaper around a pen or highlighter. 2. Curve the reed Bend/curve the reed slightly and place on the sounding board. I've found putting the smoothest side against the sounding board makes the best sound. 3. Place stopper Place the stopper on top of the reed. If you move the reed out further from the back of the sounding board it will give the 'quack' a lower sound. 4. Place tube Insert the sounding-board, reed and stopper assembly into the tube. It should slide down pretty far but not all the way. Sand more if you it is too tight. It should be tight but not too tight. Be careful here you might break the sounding board if you are too rough. 5. Try it out! Blow in the end indicated below. Try blowing really soft at first and then increase your air pressure. If it stops before make a loud sound try taking in apart and adjusting or re-curving the reed. If it still doesn't work try sanding the reed smoother. Also you could try the thicker reed. How I Designed This Software We used 123D Design as the modeling software.
