Check the listing for details. Network Switch Link Light Covers, 24W+24N RJ45, 4 SFP, Black, 3D Printed. Condition: New. Listed at 12.99 USD. Is your switch or network equipment (or anything with annoying link lights) somewhere where it needs to be as dark as possible? I designed these little light covers to help with that situation. Whether it's in a bedroom, near a pet cage, or anywhere else the lights can be distracting or undesirable. Made on a high quality 3d printer with matte black PLA to absorb the most light; these little covers will significantly reduce the brightness of the lights. There will still be some light you can see through the sheet metal on your switch and through the clear RJ45 connectors but the main LED light will be covered. The set contains 24 RJ45 port covers for wider ports and another 24 port covers for narrow ports and 4 SFP port covers. (I throw in a couple extra RJ45 ones in case they break as a bonus.) I appreciate any feedback as well about the design or any of the other stuff I sell that's 3d printed. As a designer I want to make products that actually reflect what customers want or need. Designed based off a Ubiquiti Switch and Dream Machine.
