Looking for a smooth ride? This is a Simple Circular Slider designed for 0.5" (12.7 mm) steel bearings. πŸŽοΈπŸ’¨

πŸ› οΈ Project Details

  • Ball Size: 12.7 mm (0.5 inch) marbles.
  • STL file
The Loop-de-loop! 🎒

The main feature of this design is its low slope, which provides a satisfyingly slow ball descent. It’s perfect for testing how gravity and centrifugal force interact with your track dimensions before building a larger project! πŸ§ͺ✨

Ideas:

  • Design: Circular path with a gentle, low-angle incline for a "slow-motion" roll. 🐌
  • Purpose: Experimental track to test tolerances and rolling speed on curves.
