Prompt that made this
Universal joint. Three separate parts, not grouped: two yokes at 90° to each other, and a cross-shaped spider seated in the yoke forks. Shafts 16 mm, span about 70 mm.
Made in Voloom from the prompt under the model. Sign in to download the STL, or fork it so every size on the right becomes editable — without spending credits.
Why this one
Transmitting rotation between two shafts whose axes meet at an angle.
The spider's Z trunnions seat in yoke 1's ear bores and its Y trunnions seat in yoke 2's ear bores. Each yoke can pivot about its own trunnion axis, which gives the two perpendicular axes of a Cardan joint. Torque passes shaft, hub, ears, trunnions, spider, trunnions, ears, hub, shaft.
