Fan Guard

thingiverse

Introducing a fan guard design inspired by Crazy Jaw's Lazy Fan Guard concept. I tried other designs, but none satisfied me completely. One even damaged my fan due to oversized holes. This design provides sufficient air intake while being difficult to poke through. Printed with 0 shells and 100% infill for strength, it fits snugly and is easily installed after cleaning the extruder. The 1.5mm wall thickness ensures a secure fit, but you might need to clean up the holes with a 3mm drill bit beforehand. Sailfish on my Rep1 with reduced acceleration ensured smooth printing. You'll require support for the catches, which are compatible with fans from my Bot1 (10.5mm deep). I haven't experienced any whistling noises, but high-frequency hearing may differ. Replacement fans push more air than originals and can be louder. The design was created using Cubify Invent, a cost-effective choice, processed in Netfabb, and looks great in Fluorescent Red with RepG slicing.
