Fully Customizable Gyro/Gimbal Toy
Completely customizable gimbal / gyro toy. Loosely based on some other designs I've seen floating around. This one, however, allows you to set your own clearances for a perfect print.
Customizer note:
This design seems to timeout on Customizer pretty easily. Try turning down "# of segments", or switch to cylindrical rings instead of spherical rings. If all else fails, download OpenSCAD and be prepared for a couple minutes of rendering.
