5015 fan blower vortex

thingiverse

I couldn't find a fan guard for my 5015 that I liked. I wanted a vortex or helix style. For ease of measurement (perforation spacing and rotor axis), I based myself on a model picked up from Thingiverse, but 100% of the shapes are my design. I don't claim that this shape will boost airflow, I just hope it won't slow it down. I mounted this realization on my laser engraver and modified my Anet A8. I printed in PETG because it was what I had set up on my printer, but it's printable with any type of filament without support and at a resolution of 0.2. Thank you for being indulgent, it's my first complex realization with Fusion 360, I'm more used to FreeCAD (all my other models so far).
