MK3S Fan Finger Guards
thingiverse
This is a set of finger guards for 50mm and 40mm Noctua blower fans used in MK3S printers and similar models. Please see below for printing notes. P.S. The 40mm fan guard may slightly increase the printer's noise level due to air passing through it. To minimize this effect, I kept the material covering the fan to a bare minimum. However, life is not perfect, and some compromise was unavoidable. You may also want to re-run X-axis calibration to ensure that the 40mm guard does not cause any issues. On my printer, it works flawlessly, but your mileage may vary.
