This is the completely redesign of my Modular Hub mount. The connections were changed to dovetails for a more secure connection. The Hub mount is split into two seperate designs; one with the switch one without. The phone mount is designed to use the Rev USB Retention mount to hold the cable more securely.
These mounts are made for the REV Robotics expansion hub and battery as well as a Moto G play for FTC robots. It doesn't matter which side each part goes on so long as the battery mount is in the middle. The phone mount is purposely made slightly shorter than the actual phone, as this makes it easier to take the phone out of the mount.
