Stadia Controller Z fold 3 mount holder

I needed a phone holder for my samsung z fold 3 that would attach to my stadia controller, but in the open position and with various cases.  This uses an m3 nut and bolt to capture the base, and an elastic band for the top to adjust the top.  Use multiple or a multi wound band for more tension, holds really well for me!  The bottom needs supports, as does the main body under the nut holder.
