Fits the specific WMF mill you can find at https://www.wmf.com/de/en/electric-mill-set-2-piece-3201000871.html
You may adapt this to other mills though with the attached OpenSCAD file.
I printed with PETG with 0.2mm layer height on 0.4 mm nozzle. No supports are needed and walls are so thin that infill is not used.
The author marked this model as their own original creation.
