9m Circular Ventilation Grille

thingiverse

I modelled a circular ventilation grille with a diameter of 9cm because I needed to replace two identical grilles on the outside wall of my garage that had been severely damaged by years of sun exposure. The local DIY store only carried ventilation grilles with diameters of either 10cm or 15cm, giving me the perfect excuse for an afternoon of 3D printing. I printed it with the flat face against the print bed, requiring no supports and resulting in a very fine finish. One important note: the surface in contact with the print bed is quite large, which helps with adhesion but can make removing the print from the bed challenging. To avoid damaging either the print or the bed, let the print cool down for at least an hour before attempting to remove it.
