I have seen other phone repair stands, but i broke 4 of them in a week, so i reinforced it a bit and made the lcd holding arm bigger so it will last in a retail repair environment.
This stand is for any phone you open from the lcd to repair or work on. It will hold up the lcd so you dont have to use your hands to hold it while you work on the inside of the phone.
I made 2 versions, one that is all solid, and one that has a truss like shape to it so it will print using less material. it does have some bridging so if your printer is not up to it, print the solid one. i printed with .25mm layer height and using tree supports @35degree overhang so the branches would hold up the lcd arm without having to rest on the model itself.
