A While back I restored an antique 1950s Schatz Cuckoo Clock, but the clock's original hands were broken beyond repair. I scaled EmilianoAI's hands to fit the measurements of my clock. I also used calipers to measure the brass insert from the original minute hand, savaged and inserted it into my 3D printed hands. this is the second STL upload. (I printed three with varying clearances to obtain the tightest fit.)

If you have any questions or concerns, please feel free to send me a message. I hope this helps you with your clock, and If my designs have helped you, feel free to send me a little tip. Anything is greatly appreciated and goes back in to support my hobbies. :)
