Introducing my new UFO-shaped hovercraft print, powered by a balloon!

This model is made up of two parts: the UFO hovercraft itself and a screw with the balloon attached (you need a balloon). To inflate the balloon, simply blow it up through the screw. When you press the screw together, the air will stay inside. Next, attach the screw to the UFO hovercraft by giving it a twist until it's secure. Now you're ready to let it go!

Watch in amazement as the UFO hovercraft glides effortlessly across any flat surface. As the balloon deflates, the hovercraft will eventually come to a stop, but not before providing you with plenty of fun and excitement.

It's a great way to demonstrate the power of air pressure and the principles of physics in a fun and engaging way. Plus, it's easy to assemble and use, making it a perfect activity for both kids and adults alike.

Hint: Infill ≤ 20% (I use 10%)

print with “no support”

Features:

• easy inflate over a screw
• prevent from deflating by simply pressing the screw
• the screw stabilizes the balloon

… not sealed ?

the neck of the ballon acts as a sealing, if its attached to the hovercraft. If the screw goes haywire, you can remove the ballon and roll up the neck of the ballon to make the sealing thicker.
