This is a Moto G4 Play phone holder designed by FTC Team #3736, Serious Business. After upgrading from ZTE Speeds, we found that there were very few phone mounts that build in strain-relief and versatile mounting options. We are using this on both out robot and our driver station in the 2017-2018 year and are very happy with how it performs.
Print with the flat number side facing down on the bed. Use supports everywhere to reinforce the lip holding the phone in.
