A simple clock that you can print from different colors. It is assembled in 5 pieces. Each can be modified to your liking.

I used an existing model (https://www.printables.com/model/121529-clock-face) to generate a sample clock face, but you could use anything that you like.

1. Glue Pieces 1 and 2 together. 
2. Piece 3 needs to be glued into the base of piece 2.
3. Pieces 4 and 5 need to be glued together.
4. Finally, attach the clock into Pieces (4+5) and snap-fit the entire thing together.

I printed them with 2 walls, 15% infill.
