Flexible lathe mini lathe 3D print model
For tough jobs like stainless steel, you can attach a standard flex shaft to your mini lathe.
You can use a dremel or other more powerful device. Standard size for the hand tools shown in the figures (gray and yellow). The support for the lathe is also included, I have used a metal tool holder to which I have made 4 drills and fastened it with the 4 M3 screws
