thingiverse
Connect the EqT to an inflatable sphere and begin your training sessions for Frenzel and Mouthfill techniques. Browse online tutorials for guidance or search terms like "Frenzel balloon freediving" to access instructional videos and detailed explanations. Special thanks go to MJN031, who created one of these devices and shared it on Thingiverse (https://www.thingiverse.com/thing:2221460). Although this design works well, I found it a bit too wide for my nasal passages, so I designed an updated version from scratch, with a narrower top section. Enjoy your practice sessions and never engage in freediving solo.
