You will find detailed printing instructions in the original model, or if you have a Prusa MK3S(+), you can use my pre-sliced PETG files. These files will make full use of the MK3S+'s print bed.

For the propeller, since the original author didn't provide the source file, I had to redesign the model. However, since the mathematical calculations for this problem are quite simple, it was relatively easy to achieve. My OpenSCAD file is now available here.

All model files that cannot be found in this adapted version should be used from the original model.

Update: I've added a file for printing propellers using a 0.8mm nozzle to get a stronger version of the propellers. Actually, I'm still using a 4mm nozzle for printing, but I've taken advantage of the fact that I can extrude more material. Maybe I could also achieve the same effect by extruding excessively in large quantities.

In addition, according to the user's request, I added a 3MF file for the propeller.
