Universal Duct Guards 3 Inch Propeller

thingiverse

I designed these universal 3-inch propeller protectors to prevent accidental damage against objects. Two STL files are available, one with built-in support so you can skip adding it during slicing if you're familiar with printer settings. If not, the other STL file requires supports to be added manually during slicing. I printed them in PLA but recommend printing in more durable materials like ABS for optimal results.
