The Trammel of Archimedes is a geometric structure for constructing ellipses or exploring simple and appealing mathematical relationships. It's an ideal tool for kids to ponder over mathematics, making it a great addition to any math set. The design can be easily created in Fusion 360 or other 3D design environments using the Pythagorean Theorem for accuracy. To verify that the curve drawn is indeed an ellipse, students can use this trammel to explore elliptical curves and learn about their properties. In this design, I made the sliders loose for easy installation, allowing for smooth assembly with two types of sliders available. The arm features cuts in the holes for easy assembly and removal, making it a convenient tool for math exploration. The handle is designed to accommodate a school pencil up to 8.5mm in diameter, enabling kids to turn the handle or insert a pencil for real drawing. Alternatively, users can remove the handle and create a fidget toy that's soothing and mind-entertaining. If any joint feels tight after assembly, applying a drop of lubricant will help resolve the issue.
