aperture fan cover/guards with standoffs (40mm)

I was really drawn to this design at first, but once I integrated it into my printer, the fans started making an even louder and higher-pitched noise. As a result, the fan had to exert more effort to draw in the same amount of air.\r\n\r\nBy adding supports and a central hole, I was able to ensure that the full airflow volume could pass through while still protecting the fan effectively. This design comes with both bolt-post and clip-on styles for added convenience.
