Geared mechanical stopwatch

About this part

A gear-driven mechanical chronometer model that counts from 0 to 999 and then loops back to zero. The mechanism is driven by an 8 g micro servo; the on/off switch is on the simple electronic circuit. It can be displayed horizontally or upright on its stand. This listing includes PETG FDM 3D printed parts produced by Eksenix; color is selectable. Non-printed parts (8 g micro servo and 1.5 V AA battery) are not included. Basic hand assembly is required. Please compare the listed part dimensions with your components before ordering.
