Description

PDF

I took jzisa's V29 as a reference for the inner chamber. I designed a new shell from scratch aiming for a compact, elegant result. I also added a hole perpendicular to the print layers for increased strength. It accepts a keyring or a cord.

The grip is excellent and it comes with the SOS signal on the bottom side of the whistle.

 

Bonus: You can use the top side to emboss your own name or logo.

 

Dimensions:

  • 5 x 2.6 x 1.1 cm
     

Printing:

  • 2 Walls are sufficient, use 3 for added strength.
  • It can be printed without supports. 
  • Optoinal: you can add supports only to the bridging on around the back hole. 

*You can test your printer capabilities with my QuBenchy - 3D Printing Torture Test Cube:

 

Power:

  • This design uses a similar chamber as jzisa's V29, which claims 118.7 dB. Be mindful when using the whistle.

 

Feedback is welcome. Cheers!

Complete redesign of the shell and partial redesign of the interior cavities. Addition of SOS code and hole is now perpendicular to print layers for increased strength.
