Star Fidget A parametric star fidget featuring nested hollow rings and a solid center with an integrated handle. Sharp, outward-chevron walls keep the components captured while allowing independent movement. Customize the tip count, proportions, component count, wall thickness, clearance, and handle dimensions. Defaults to 120 mm across with coplanar bottoms for print-in-place fabrication. Movement depends on printer accuracy and clearance settings.
Original prompt:
Create a parametric print-in-place star fidget: 10 hollow rings and a solid center with a fused cylindrical handle.
Generate a symmetric star outline mathematically, with equally spaced tips, identical straight tip-to-valley segments, alternating tip and valley radii, and one tip along +Y. Make tip count and inner/outer radius ratio editable.
Use outward chevrons widest at mid-height, with straight sloping walls. Measure wall angle from horizontal. Measure wall thickness and clearance at the valleys: thickness through the wall and clearance between adjacent components. Profiles must retain separate, independently moving components.
Editable defaults: 12 tips; radius ratio 0.8; 11 components; outer span 120 mm; angle 50° from horizontal; valley wall thickness 0.8 mm; valley clearance 2 mm; body height 10 mm; handle Ø8 mm, extending 22 mm above the center.
Keep bottoms coplanar and edges sharp.
