This is a compression screen phone holder I made that attaches to the homemade 3D scanner I am working on. The holder is designed and assembled to hold well with snap and press fits. If you want pieces to fit tighter you can glue the Upper and Lower Housings to their respective housings after assembly. 70mm long 2mm diameter steel rods and a 36mm to 40mm tall spring with an 8mm OD is needed to have a good sliding action that holds a phone.
