This is a remix of an original Balloon Helicopter, but without a need of straws. The wings have adjustable mechanism to enable rotation

There are 2 parts:

• helicopter
• balloon connector - inserted into helicopter part

How to use:

1. Print both parts, if you haven't already printed original balloon helicopter 
2. If you have balloon connector from original balloon helicopter, it can be used here
3. Wings can be rotated - adjust wings to a certain degree - optimal is one rotation: 30deg.
4. Blow the balloon and connect to helicopter
5. Have fun!

Optimal print settings:

• .2mm layer height on .4mm nozzle
• at least 3 perimeters (walls, top, bottom)
• turn off build plate adhesion so the helicopter can fit to plate
• make sure you have good tolerances (.3mm) or the wings will merge with the base
• you could use a smaller model from this to test tolerances
• should print for about 1h30min
