The Timing Chains - Mechanical Digital Wall Clock
Description
## Decorative mechanical digital wall clock is introduced. ### Features - You can make this clock with small 3D printers. Maximum part measures 151 x 90mm. - Relatively easy to make. Number of printed parts is 42. Chains are partially print-in-place, and connection of links is snap-fit. - Easy time adjustment. - Digits are highly visible. Without painting or glueing, it automatically combine white letters and black background on top. The digits are a bit slanted. ### Operation - One minute advance with reset button of micro computer - Fine position adjustment with reset button while the motor is running - 10min. and hour digits can be adjusted (rotated) by your hand From technical point of view, the highlight of this clock is a carry up mechanism that can handle any base of the numeral system. In actual, 10min and 60min carries share the same mechanism. The only difference is the length of the chain. To design the gears, I used "Precision Gears" addon for Blender, https://makertales.gumroad.com/l/PrecisionGears
