140mm Fan Grill Cover Protector

thingiverse

I designed this fan cover for a custom project, where I converted an Ikea glass display case into a terrarium for orchids and other high humidity plants. I used a Noctua NF-A14 Industrial fan on the top of the terrarium to create a bit of airflow, and I didn't want my cats to hurt themselves whe they would innevitably step over it. The holes should be the correct to attach directly to the fan, however to be honest I didn't try as I ended up sandwiching the top of the unit between the fan and the cover. If you see that you require different hole spacing or sizing let me know. Current sizing: * 2mm-2.5mm width screws with 5mm inset head * 124mm hole spacing between the 4 holes (around the circumference) * 175.362mm hole spacing diagonally Base: * Print with the fillets facing up, the screw insets will be visible from above also Cover: * Print flat side down with the ribs sticking up * The cover slots into place inside the gasket/base with ease, yet it should hold (using 0.15mm tolerance between each wall, though I designed it with lips so that it should be ble to work with higher or lower tolerance machines) * I attached two designs, a flat basic one and the one I am using, which has the design of an orchid plant etched into it Print with any layer height you are comfortable with, I personally ued Smartfil PETG @ 0.2mm layer height.
