3D printed ball clock
The clock is based on a design from the ’70s by Harley Mayenschein, using marbles on three different rails to give a readout and to track time.
Although my design is more optimized to be smaller and uses an original lifting system using a bar mechanism.
It is quite accurate, it has an error of 6 seconds in 24 hours
In the following video the operation and assembly of the clock is explained:
