ClickyBolts
thingiverse
Humans utilize 4.4mm x 8.7mm PLA snap-in bolts to secure a 4.75mm thick fan screen firmly in place. Update: After Cavey's suggestion, sides of the bolts are sliced off for printing, allowing them to lie flat. Four different lengths ranging from 8mm to 10mm are posted, measured from the bottom of the head to the top of the clickers.
