I am a huge fan of Duane777's design for the phone holder v3! Unfortunately my car has vent positions that make this very awkward. So, I remixed to include a ball mount and a universal plate that can be mounted with 3m tape anywhere with a flat surface.
Instructions
- Insert the ball part bottom-first through the nut.
- Screw the base-plate to the bottom of the ball-part. You may want to add some super glue here as turning the nut may have a tendency to spin the entire cylinder once you have mounted
- Depending on the weight of your phone, you may need to line the ball mount with something like teflon tape. Mine worked fine printing as is, since I have made the washer part of the nut.
