Travel Trailer Ethernet Pass-Through

This is designed to replace the coaxial input/output ports commonly found on travel trailers and RVs, allowing you to repurpose those ports for Ethernet connections without modifying or adding new holes to the trailer. The design is reversible, so you can easily switch back to using the original coax ports if needed.

We recently started using Ethernet for connectivity, whether docked at home or when utilizing Starlink on the road. This design seamlessly integrates Ethernet into the trailer’s existing setup, offering a simple, clean, and functional upgrade for modern connectivity needs.

I printed this using a Prusa XL with a 0.6mm nozzle and 0.15mm layer height, using PETG for durability. No supports were used, though the apex of the internal arch has minor imperfections. If you want a cleaner finish in that area, consider manually adding supports during your print setup.

We used this RJ45 Panel Mount from Amazon as the passthrough. 

The photo showing this installed on the trailer is an early prototype and looks slightly different from the final.
