Summary

UPDATE -- Scaled up by 5% and added a seal to be printed in TPU, if required.

For additional sealing around the cable entry, I just recommend bombing it up with hot glue around the cables and then putting the lid on.

Remixed to remove the internal raised base and rescale the original file.

Should fit majority of receivers.

To create a form of seal/gasket, I ran some E6000 around the outside edge of the lid and let it dry.
