Springy Topsy Turvy Top

thingiverse

This long-spinning top boasts a spring-loaded suspension built into its bottom, guaranteeing incredibly smooth motion - and when running is that smooth, spin times grow impressively longer. Like its relative (https://www.thingiverse.com/thing:681860), it prints seamlessly in a single piece, flipped upside-down from start to finish. **Directions** Made with PLA filament at 0.2mm layers, this design incorporates 3 perimeters, 3 bottom layers, and 4 top layers, while using 50% infill for strength and stability. Fortunately, no support materials are needed - a clever feature indeed! The spiral suspension spring does create a tangled mess on the underside as it goes, but by the time you reach the uppermost layer, the tangles clear up remarkably well. It is advisable to employ an x-acto knife to sever any loose filament strands lingering about within the spiral itself.
