Space Time clock

the Clocks body, legs and hand shaft can be printed without supports. The hour, minute and seconds hands must be supported.

Assembley: glue hand shaft with the flat surface to the inside of the clocks body making sure it is centered. Install an appropriately sized motor and shaft in the back of the body. 
drill holes into the hands according to the size of the mothers shaft ( you will see a tiny hole in the center of each hand for guide).  Leave space between each hand for its free movement.

place a dab of glue to top of legs and insert into clocks body.
