d20 spinner 3d model

Create a functional dual-axis D20 spinner that works as a mechanical gimbal assembly, fully printable in PLA using an FDM printer with no slicer supports. The design must be print-in-place, meaning all parts are connected by clearance gaps and move freely after printing. Assembly overview (3 parts printed together): Central part: a perfect geometric D20 die, about 40 mm across, centered in the design. Inner gimbal ring: surrounds the D20 and allows it to rotate left–right.  – Connected to the D20 by two cylindrical pins passing through opposite vertices of the die.  – These define the first rotation axis (X-axis). Outer gimbal ring: surrounds the inner ring and lets it rotate front–back.  – Connected to the inner ring with another pair of cylindrical pins, positioned 90° perpendicular to the first axis.  – These form the second rotation axis (Y-axis). There should be two rings and do not include any text or numbers.
