Printed On Bambu Lab X1-Carbon Using Filament eSun PLA+
Printed without Supports, Printed without Rafts, Infill 20 %
This mechanism converts rotary motion into uniform back-and-forth linear motion using intersecting reverse grooves on a rotating cylinder. A pin trapped in the groove moves from end to end as the cylinder turns. Designed for demonstration and learning.
