Ford Transit Phone Mount Base and Ball Mount

I designed this mount block and ball mount to work with the phone holder that came with a expandable cup style phone holder.  This fits my 2021 Ford Transit 250.  It will slide in behind the stock radio and holder firmly.  The curved post is printed on it's own and screws into the base with a 5/8"-11 thread.  I used a tap and die to chase these threads prior to fitting them together.  I also recommend a small amount of grease on the thread so it will not bind.  If you need a phone holder, there is a 17 mm version of one on maker world and it fits the ball mount well.
