RAM Mount Adaptor

This is a modular Ram mount system adapter to mount generic phone holders like the ones sold on Amazon. One side is a 1" Ball and the other is a 17MM ball. The wireless charging phone holder I have has a receiver on it, rather than a ball, so this is a work around for that. Since I believe the stem would be too weak if I printed it. I use an aluminum spacer from McMaster-Carr and a screw a nut to make it much stronger. This design will work with other size balls, but I only made the ones that apply to my situation. I recommend using PETG do to it's heat resistant properties.
