Rack Mount Cable Modem Shelf

My awful Arris CM820A cable modem is too tall to fit in a single U, so I came up with this 2u shelf to hold it. Also includes a hole for a keystone jack, so you can run ethernet to the front of the panel.

The shelf attaches to the faceplate with M5 screws
I made the shelf with some additional holes for zip ties or whatever if you can't get the mounting screws to work (it was a pain to find hardware that would hold the modem to the shelf)

I designed this for my CR-10 S4. If you have a smaller printer, you'll probably have to break it up into more smaller parts.
