Arris Surfboard S33 S34 10'' Rack Mount Horizontal

A horizontal 10'' (10 inch) rack mount adapter for the Arris S33/S34 Cable Modems.

The original model on MakerWorld was here:

which in turn was a remix from here:

I also used the following 1U base to create the 1U front panel:

NOTE: The Arris modem is slightly larger than 1U.  In order to accommodate it, I used an offset to push the modem back a bit but there is a lip that extends above/below the 1U panel.  This allows it to fit above the fan mount I have below it.  But this will HIGHLY depend on your situation.  Thankfully you can just flip it and decide if the >1U part is on the top or bottom.

It does need support enabled to print and came out well with my PETG filament.
 

As with the original, you will need additional hardware to attach the endcap to the main frame.  The below were listed from the original model:
4x M3 Threaded Inserts (L5 would be most ideal but any length is acceptable)
4x M3-.8x10mm bolts 

Or if you're lazy like me just use some fan screws you have lying about.
