thingiverse

This is a fully functional and highly customizable Mosaic inspired 120mm PC fan guard that can be easily printed on any MakerBot using either PLA or ABS material at various default settings, including high, low, and medium. Thanks to its unique design, this guard doesn't require any support materials, though a raft may be necessary for prints made with PLA. Once the printing process is complete, you can secure it in place using standard PC fan screws.
