Solar Watch Movement No Battery Model 3D Print file
This is the 3d model of a solar watch.
The sundial displays time (with actual digits !!) from 10:00 until 16:00, updating every 20 minutes.
You can precisely adjust the displayed time simply by rotating the gnomon (the magic box that displays time). So you can even adjust for Daylight Saving Time.
You’ll also need :
— an (empty !) jam jar
— 3x M6 screws, flat head, length = 20 mm
— 1x M6 screw, flat head, length = 50 mm
— 4x M6 nuts
— 4x M6 washer, outside diameter < 14mm
