RJ45 Dust Cover-Keep the Gunk Out of Your Gigabits

Dust belongs in the vacuum, not in your Ethernet ports.

Ethernet ports work hard, so don’t let them choke on dust bunnies. This 3D-printed RJ45 port dust cover is the quick, no-fuss way to keep debris, crumbs, and mystery particles out of your networking gear. Whether it’s a home router, a patch panel, or that ancient switch you swear you’ll replace “next week,” these covers slide right in and protect your ports like tiny bouncers at the club.

Why you’ll love it:

• Keeps dust, dirt, and stray static-charged pet hair out of unused RJ45 ports
• Easy press-fit design. Easier than plugging in a cable.
• Reusable and durable when printed from TPU.
• Works with standard Ethernet ports on switches, routers, and patch panels
• Saves you from awkwardly explaining to IT why there’s potato chips in port #3

Printing Notes:

• Material: TPU recommended. Don’t risk other plastic breaking off in your ports.
• Layer height: 0.2 mm 
• Infill: I went with 12% for flexibility
• Prints in minutes. Fill up a plate if you work in a data center.

Print this RJ45 dust cover, because nothing says “network downtime” like dust where data should be. 🖧✨
