About this print
A mechanical model demonstrating how rotary motion is converted into linear motion, based on mechanism 329 from the 507 Movements collection. The geometry has been corrected to produce a more truly linear output, making it a useful teaching aid for engineering and STEM lessons at secondary school level. A complete set of STL files is provided so all components can be printed and assembled into a working model. PLA is a practical choice, as the model is used for demonstration and educational display rather than load-bearing work.

This is a reworked update of Things 614962 and 652717.
The geometry has been corrected to give a more truly linear output, and some fixing points have been enlarged for greater robustness.
A complete set of stl file have been uploaded here.
The model is based on mechanism 329 from 507movements.com.
Designed in Moi and made in PLA on an Ultimaker 1.

Printing Rotary to linear drive
For Rotary to linear drive we would normally reach for PLA — it is the easy, economical default and suits the majority of models. We set the layer height, wall count, infill and supports to suit the model and how you will use it, and those choices are already priced into your instant quote. Want a specific colour or material? Tell us and we will match it where we can.
