This is a 10 inch rack mount for a TP-Link SG105. I have printed it whit ABS. No support needed, I have added a custom support in the model.
If you need a 10 inch rack mount for a different brand or you just need a cover plate I will highly recommend you check out https://www.printables.com/model/641736-10-inch-rack-project.
