I also had one port that came loose. I was able to resolder it since the pads were intact.
The problem is that the connector on my board is not using thru hole solder pins that can handle larger forces.
- Modify the 3D model and extend material to support the cable. It becomes quite bulky but could work.
- Solder a wire over the connector and attach it tightly to the backside of the device. Heating the wire will fuse it to the PLA.
Epoxy glue is probably not a good idea, since it risk filing the connector and preventing cable connection.
