Single-Turn Helix

Because of the very low slope, the ball rolls at a satisfyingly slow pace, making it a perfect desktop "fidget" or a calming visual experiment. 🐌✨ At the end of the descent, the ball exits the track through a specialized exit tunnel built into the outer wall!

🛠️ Important Post-Processing Tip

To keep the design compact, the exit tunnel has very tight tolerances. ⚠️ Note: Depending on your printer's calibration, you will likely need to sand the inside of the tunnel with a small piece of sandpaper after printing. This ensures the 12.7mm ball passes through smoothly without getting stuck! 🪚🪛
