Remix of @DevineJimmi ‘s 10 inch ER605 rack mount, I’ve added a couple of keystones to help with routing WAN etc in my mini rack. Removed the text too to make it easier to print for me (hope that's ok, please check out the original!)
Keystones purchased from aliexpress, I assume most will fix but double check the dimensions if you do purchase! I got these ones https://www.aliexpress.com/item/1005006728475384.html
The author remixed this model.
Added one keystone on each side of the router mount for routing WAN/other connections. Removed text from the model to make it easier to print for me
