Spirometer – learn to play air instruments and improve your breath and resistance

Features:
✅ Works with standard trumpet mouthpieces
✅ Trains airflow and lung control
✅ Lightweight and portable design

Perfect tool to boost your air instruments skills!

Assembly:

the finished object should look like this:

I used a little silicone on the big white part to prevent any air leaks.

finally insert your mouthpiece and you're done.

Recommended Materials:

I used Sunlu PLA+ for orange parts,

bambulab PETG for trasparent part,

Sunlu TPU 95A for white parts

You can use any material you like, as long as you use a transparent material for the tube where the ball will be inserted. I also recommend using TPU for the white parts, as they need to be snapped together, and TPU prevents air from escaping.

Print Mode:

Use my provided .m3f template if possible (on print profile choose the one that says "DESIGNER"). This model is already configured for best printing results.

Orientation and Support:

The object can be printed entirely on 3 plates on all printers.
supports are only in 2° plate

USE:

Try to keep the ball high when you blow into the mouthpiece to improve your breathing, resistance and to achieve a stable flow

The two rings are designed to adjust the ball's resistance level. The more holes you leave open, the harder you'll have to blow to maintain the ball.
