New upload: Gliding Manta Ray! This 3D printed manta ray comes to life in water You need to hold it underwater and release it flat, then it smoothly glides forward like a real manta ray. No motors. No electronics. Just physics. Would love to see your prints and videos! #ChildrensToys #Contests 👉 Full model here: https://makerworld.com/en/models/2909692-gliding-manta-ray-just-drop-go#profileId-3254038

I wanted to create a simple toy that combines fun and science. The idea was inspired by the classic floating ball toys that demonstrate the Bernoulli effect. My first prototypes worked, but they required blowing too hard, making them difficult for younger children to use. After several design iterations and airflow adjustments, I finally achieved a version that was much easier to play with. One feature I'm especially happy with is the built-in storage compartment. The toy unscrews so the ball can be stored safely inside when not in use, helping prevent it from getting lost. The result is a compact toy that is easy to print, fun to use, and introduces basic physics concepts through play.

Hey makers! 👋 I’ve just uploaded my latest project to MakerWorld — a highly detailed 3D printed radial engine! It’s 250 mm in diameter (scalable), printed in PETG, and designed for easy assembly. You can use it as a decorative piece, a static display, or even integrate it into RC airplane projects. In my case, I mounted it on a pedal airplane I built for my son, and it looks absolutely awesome! https://youtu.be/YxoAaV_0UMk?si=3OwBebat1GVaCAAh
