A clock to help my kids learn how time and clocks works :)
Its made for a clock with about 20cm ~ 9in long arms.
The outer diameter of the ring us 46cm ~ 18in
The max. diameter with numbers is about 53cm ~ 21in
To find the clock you need to look up "clock quartz mechanism" on ebay or where ever you buy your bits and pieces.
If you want the minut markers in another color (as in pictures) pause the print at 3 mm and change filament.
