Descrizione

Geared Learning Clock

Mechanical clock to teach children how to tell the time. Prints without supports and assembles without glue or screws. Change the time by turning the minute hand or the protruding gear at the top. Internal gears maintain the 12:1 turning ratio for the clock hands.

Enjoy!
