Organettissimo

We are 4 french high school student, from lycée Maxence Van der Meersch in Roubaix (FRANCE) interested in sciences.Our idea, at the beginning of the creation of "the organetissimo", was to create an instrument easy to carry out, low cost and easy to assemble, but also repairable.

we choose the 3D printing technology because of the democratization of 3D printer, available in fab labs and universities in order to give students the access, and possibility to build our instrument everywhere, and even travel with it. 

Based on this instructable (https://www.instructables.com/Four-Whistles-Version-2/), we've upgraded it and redesigned it to create our own prototype, with a work mostly oriented on the tubes and the opening's shape, with the goal to create the optimal instrument that produces a better sound in terms of quality and intensity. Indeed, not only the lenght, but also the window length control the tone.

We also designed elementary base system to not be limited in terms of tones wanted.

The organetissimo is an adaptive instrument, so you can print only the pieces that you’ll need in function of your musical score!

We printed all parts on a 3D printer "Magis" by Dagoma, with 33% infill.

you will need to purchase a foot pump to complete the instrument.

to print the element, be careful of the best printing direction as shown on pictures.

for smallest part siche as "tige-actionneur" or "jonction" and "actionneur", sanding is required definitely .

We managed to print everything without trimming, except "embout-pompe" but you should try and find your own parameters.

for one tone, print everything once.

print one more "base.stl", "tige-clavier.stl", "tige-actionneur.stl", "touche-clavier.stl", "actionneur.stl" per supplementary tone wanted.

choose the files depending on the tone wanted.

prefer horizontally print for the tube, the window on a side, in order to have the cleanest design fot the lip.

Each tone need a "piston.stl".

Here are the tone to play like on the video. More will come!

Once your tubes, exciter tips, keyboards are printed you can put together all the pieces and build your brand new organetissimo ! 

Assembly si very logical, like a puzzle.

"jonction" is required between two base.

Also, sealing is important to keep presure. the “Patafix” or Blu-tack will be your best friend ! Don't hesitate to put the dose, the less there is air leakage, the better your instrument will sound. YOu can use glue as well but then you won't be able to desassemble ans replace the only part broken. The choice is up to you!
