Introduction: The 3D-printed Watch
How to build your own watch?
The video shows one way to realize the idea of your self-made watch. Before you can start the only parts you need to buy are the clockwork, the glass, the cover of the watch and the cylindrical pins to connect the chain moduls. For this project I used 1.5 mm pins. I bought the clockwork and the main parts of the watch at the flea market. It's easy to find old watches there for a good price.
Step 1: Construction of the Watch
If you have all parts together it's about constructing the rest. You can start with the watchcase. For this you have to messure the clockwork you've bought. The height and the diameter are important. Be sure that there is enough space left over for the cover and the glass of the watch. The rest of the design is up to you, but don't make it to thin!
For the connection of the chains you should use the given measurments from the uploaded pictures. They are all just for the 1,5mm pins. Iam using an Ultimaker2 and for this printer it's working. For one side use a bigger diameter that you can move the pin easy, for the other side a smaller one that the pin is fix. The same diameters for the connection with the watchcase. To open and close the chain frequently I've constructed a kind of a backpack buckle as you can see in the image above. You'll need some time and experiment a bit to figure out the right sizes.
Step 2: Printing
The printing is easy. The print settings have a layer height of 0.1 mm and only the buckle module needs support structures. The material is simple PLA filament and with it you can do whatever you like: different colours and sizes!
Step 3: Assembly
Be careful! PLA breakes easily. I used a small hammer and a solid underground to knock the pins in the chainparts. For the assembly of the watchcase you should just use your hands. First the clockwork, second the glass and last the cover. Connect it with the chain and your watch is ready.
