Mechanical digital clock

#### 4 digits, 24hour-notation (military time) mechanical digital clock controlled by micro:bit and only one RC servo motor. Time adjustment from PC is possible via bluetooth.

#### Tips to make the clock with STL files

- ALL STL files can be printed out without supports. Please arrange them with flat plane facing down.
* Bottom case : front panel should be facing down
* Rectangular axes (servo axis and selector axis) : horizontal
* Display axis (cylinder shaped) : vertical
- The last number of the STL file name is the necessary copies for a single clock. For example, please print four copies of display-4.stl
- Four copies of each digit number (1.STL, 2.STL, etc.) should be printed out with any material of different color (ex. white).
- Generally, large parts should be printed out in light weight (typically two layers, less infill). The inertia of number wheel matters. Contrary, smaller parts should be relatively tough.
- You may need some work (carving, slight bending,
