In-place printed clock. Showing minutes and hours, Orologio is made of 2 external rings, the one in the background, fixed, serves as a guide rail of the planetary gears. The planetary gears are driven by the carriage, which performs a single revolution every hour. The ring that shows the hours has five teeth less than the rear one, and as every hour pass, it performs a 30 degrees rotation clockwise and a complete revolution every 12 hours.
The planetary gears are kept in place by the carriage which has a shaft with a chamfered shaft that works as a warranty, in fact, the simple shaft passing through the gear and the shape of the teeth would assure the correct positioning and lockage of the gears.
I'll upload the single carriage as a single file if you want to print it with a different colour, but the chamfer won't be present for obvious assembly reasons.
The carriage has a hole that allows the use of a 5v motor to control the movement of the minutes.
Orologio can be printed in-place with layer height=0.2. supports are needed but are easy to remove with an Exacto knife. Since the gap is 0.2mm do not use distance between supports and top or bottom layer, so you'll create a grid easy to be removed (see sliced figure)
