I borrowed this idea from a toy my son has called a 'Saxoflute' and made the pieces to be compatible with it. I have mirrored some pieces and added several of my own design. The raised holes on the finger pieces make it much easier to play. The whistle part works fairly well but could perhaps be improved. I am not a trumpet player, but I thought having a trumpet-style mouthpiece might be a fun addition. The 180-degree and 45-degree pieces did not play well when printed--I think the inner surface may have been a bit too rough, not sure.
I would love to see others make creative additional compatible pieces, so please share if you do! One piece I have in mind to make is a trombone-style slide. Perhaps someone else can beat me to it?


Everything prints without supports except the 180 bend. That one requires a bit of support, but I was able to print it successfully using Simplify3D. All parts were printed in MadeSolid PET+ on a Type A Machines Series 1 (2014 model).

I have printed mouthpiece and 1finger piece at 100% but it doesn't fit neither. I am pretty sure it can sound really good but for me it would be useless if I have to adjust the pieces after the print as i am searching for some "print and play" instruments ! Would you have an edit or STP files as you suggest it ?
Anyway, thanks for this awesome project. I am surprise nobody already made it.
It reminds me of a great french artist who does stuffs like this with pvc tubes. I thought you could like it !

can you have sound of it playing??? REALLY interested =D

I have printed mouthpiece and 4fingers piece in 80% scale (for small girl) from PLA. But it doesn't fit in this scale. Are there 0.2 mm gaps between parts in 100% scale? EDIT: After sanding, cutting and using force it fits (partly). ;)

Sorry to hear that. Not sure what a "proper" gap would be since that is to me a bit part and scale dependent---especially for something like this that should have a tight fit. Even at 100% it does fit tight, so I am not surprised that at 80% it is too close to fit. I would be willing to send or upload STP format files for those parts if you want to edit.

Just uploaded a flute-style mouthpiece. I haven't printed it yet (and I am not a flute player) so I am not sure if the dimensions are quite right to play well--thought I would share anyway...

Updated the 180 bend piece--forgot the original was too long on one side.
