Vetus anemometer rotorhead ancient model before about 1985

thingiverse

My friend's old VETUS anemometer on his sailboat is over 35 years old, and when the original part broke, he couldn't find a replacement anywhere. He told me that this instrument has been with him for decades, and I just had to take on this challenge. I was motivated by the promise of a cold beer, but somewhere along the line, I made a mistake in the FreeCAD file - something I'm still figuring out as a beginner. You'll see a brick under each rotor that I printed; if you can spot the error and fix it, please send me the corrected file. For now, just disregard those three little bricks. You might be wondering if you have an identical instrument on your sailboat. Look for the generator with a bearing on top - that's how to identify it. I've added a screenshot to show how I arranged the parts in the slicer to avoid any supports.
