Two of the change gears in the thread-cutting / feed gearbox on our Emco Maximat Super11 lathe at Stockholm Makerspace had broken teeth after a crash, and spares were very hard to get, so I designed and printed these change gears.
They were printed out of Taulman 680 Nylon, Installed about a year ago now, and they are still running well.
The author marked this model as their own original creation.
