Phone holder for Estes launch controller

This allows you to attach your phone to an Estes launch controller for model rockets. The launch controller requires 2 thumbs to operate.
This will let you video your launch if you don't have anyone around to help you.

Put the holder on the controller, put a rubber band over the phone, and voila! hands free recording, and both thumbs can operate the safety key and launch button.

It could use a few tweaks, but it works as is.

You will need to cut a slot in at least one of the ears to attach the rubber bands. Easier and stronger to print it like this and just cut an ear.

For future improvement.. make some "pegs" on one end of the sleeve to help hold the phone in place. Maybe add another set of ears for a 2nd rubber band.
