Rackmount CenturyLink C3000Z Modem Enclosure

This design completely replaces the stock enclosure on your CenturyLink C3000Z modem, and allows it to be rack mountable. It is expected to be used in a scenario where you have your own firewall, switch, and access points, and just need the modem to run in transparent bridging mode. Basically, you want it to just be a DSL modem, and nothing else. Note that transplanting the modem to this enclosure will require desoldering the 2.4 GHz antennas, and disconnecting the 5 GHz antennas (which oddly are not soldered). This process is likely reversible.

I've only printed this one, and found the tolerance between the top and bottom of the case to be extremely tight. I made some adjustments, but did not re-print the model. If you print it, please leave a review letting me know how the tolerances are.

Transplanting the modem from the stock case to the rack mount enclosure will involve taking the modem enclosure apart, disconnecting the mc-card connectors that are used for the 5 GHz Wi-Fi antennas, desoldering the coax cables for the 2.4 GHz antennas, and removing the circuit board. If you want to put it back in the enclosure someday, I think you could resolder the 2.4 GHz antenna connections. Note that removing the antennas means that this will no longer function as a wireless router. I would also recommend either putting the router in transparent bridge mode, or at least disabling the Wi-Fi radios completely before disconnecting the antennas.

You will need:

• x8 M3x10mm screws (longer would probably be fine)
• x8 M3 nuts
• x4 M3x10 to 25mm screws
• Rack mount screws and cage nuts
