The file 'New Improved Axis 3D Printer Model' is (FCStd,stl) file type, size is 221.8KB.
I just remixed the axis to a) avoid it to slide laterally and b) to grab the rubber band.
The propellers and the boat remains the original ones.
New version with better grip for the rubber band, on the central hub.
I also added the FreeCAD file so that anyone can modify it.
