Lightweight 40mm fan grille

thingiverse

For those who want to shave every gram off their printing head in order to fight ringing, or simply want some new stylish grilles to give their printer a makeover, here is a compact and low-noise replacement for the popular iron fan grilles.\nIf you print this in ABS with no infill, no more than 2 shells, and thin extrusions, you can get this to weigh 1.20 grams or maybe even less. The iron grilles on my printer weigh 4.14 g each, so by replacing both, I can lose 5.88 g. That's a significant reduction in weight that helps to reduce the inertia of the printing head and the wobble when it takes sharp corners.\nThere is a 3 mm thick model and a 4 mm thick model available. The latter will require slightly more material but it places the grille 1 mm farther from the fan, and this reduces noise even further.\nI also offer models that have built-in 3 mm stand-offs. If like on the FlashForge Creator Pro, your fan grilles are mounted with those tiny 3 mm tall rings that always seem to fall and get lost in some nook or cranny of your printer when you disassemble the extruders, then replacing both the grilles and the rings with this single 3D printed grille will eliminate that problem forever.\nAs you can see on the photos, the right fan is mounted with nylon screws. This is because the stepper motor is not mounted, only a dummy placeholder to trigger the endstop. Using nylon screws in this case helps to shave off another few grams. (Of course I use metal screws when I need to mount the stepper for dual extrusion.)\nThe starting point for designing this was a grille generated with Customizable Fan Grille by DanielStein.\nPrint Settings\nPrinter: FlashForge Creator Pro\nRafts: No\nSupports: Doesn't Matter\nResolution: 0.1 mm\nInfill: 0%\nUpdates\n2019/05/19\nAdded 4 mm models and models with built-in stand-offs.
