Prompt that made this
Lead screw and nut. Three separate parts, not grouped: a 12 mm trapezoidal screw 80 mm long, a square nut on the thread, and a pillow block the screw turns in.
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
Linear actuator that turns rotation into straight-line motion, for example a small printer or lab slide.
The screw journal turns in the block bore. The block face takes the axial load at the thread shoulder. The square nut rides on the thread and is kept from turning by its flats.
