Ways to support.

We had an issue last year with one of our motor controller disconnecting from the USB even though they were supported with 3d printed supports. We chose the last resort option which was super glue the mini USB plug (the plastic surrounding the connector, not the metal itself) to the plastic on the motor controller, super glue the support to the electrical board, and zip tie the entire thing.

3 months later (without failure), we just broke off the super glue and everything was fine.
