This is a collaboration project with Peter Groll from Munich. From his first 3D printed prototype we managed to design a 3D printable 30 days seconds pendulum regulator pulley clock.
The clock features a retrograde hour indicator. We have several ideas for cases and wall brakets. This will be to choose for the individual. For the time being I go with the 3D printed wall braket with an acryl glass cover. The simulation in Fusion 360 showed that the braket has a more than 15 times safety for the total weight of the clock, pendulum and weight. The minute hand has a magnet based friction system to change time while the clock is running. The weight lift will have a counter lock to keep the force steady during lifting.
The hole story was discussed at the Uhrenwerkstattforum.
