This is a mechanical clock that really works. It's build out of 41 pieces in each a different slicer tab to make each piece in your preferd collor, it's a bit difficult to construct so I linked a video how to build it (sorry for my accent).This mechanical clock demonstrates that 3d-printing is not just for decoration. It's possible to create intelligent, living things.

The clock has an anchor escapement, and a balance-wheel with a spiral spring. The clock shows Seconds, Minutes, and Hours. The winding has a nested planetary gear, which allows that the clock continues to run, while winding up.

Everything is 3d-printed (even the spiral spring), except e few small screws, some metal pins, the cord, and the lead for the weight.Some parts require a loose clearance (hollow shaft for hours and minutes), other parts require a press fit (hands). The 3d-files are optimised for older printers with more inaccuracy in xy, or a badly guided z axis. I.e. when printed with a newer generation printer, parts are most likely too loose. In order to compensate this, the material flow could be increased (over-extrusion). In Simplify3d there is another useful parameter: process settings / advanced / other / horizontal size compensation.

These are the parts included:

Pins:

1 x Balance wheel: 1.5mm diameter, 40mm length1 x Escape wheel: 2.0mm diameter, 28mm length1 x Reduction gears: 2.0mm diameter, 60mm length1 x Drum Transmission: 3.0mm diameter, 60mm length1 x Drum Axis: 3.0mm diameter, 60mm length1 x Crank transmission: 3.0mm diameter, 30mm length4 x Planets Axis: 3.0mm diameter, 39mm length1 x Weight Axis: 3.0mm diameter, 15mm lengthScrews:

These are the extra parts you wil need:

6 x Frame: M3, 12mm, Flat Head5 x Winding Drum: M3, 10mm, Flat Head

Thanks for buying my model and good luck building your clock and be sure to look at my other creation.
