Easy-Inflate Balloon Valve (Print In Place)

When you stick this in the front of a balloon, it doesn't let air come out, but when you blow into it, the air goes into the balloon, helping you blow it up.
This design isn't completely air tight, so the balloon does eventually deflate, but it takes a while. I tested how long it could last before completely deflating, and it lasted up until just under 10 minutes before completely deflating.

This is a repost of my old design. Old design in credits

How to Use

1. Take it out of the 3D Printer
2. Wiggle the bottom flap loose if it is stuck
3. Insert the flap end into the neck of the balloon
4. Blow into the balloon and test it out!

If you do not have a 3D printer and still want this thing

Print Settings

• Highest print quality for best seal
• Any kind of filament
• 100% Infill for best seal

Optional
Use a knife or sandpaper to rub off any bumps getting in the way of the flap at the bottom to seal better (This is what I did before timing how long it could last)
