Trying something different, instead of something that you have to tighten down, I decided to try using spring tension to hold a phone while attached to a tripod. In the build there is 3 holes to attach this to a tripod or an arm of you're creation using qInch parts.
In one picture I have 3 inch bolts as a rail system that allows the extension part move up and down. This is enough to hold a phone in place while using the highest placement to hold the spring. In the next set I have 6 inch bolts and using the lowest placement which can easily hold a 7 inch tablet.
Hardware Used
You should be able to find usable springs at homedepot or whatever local hardware store. The springs I used for this project was from a set I ordered from amazon, its has a decent amount of variations for DIY projects.
