Phone holder for VW Beetle
Just print vw-bug-phone-holder-clamp.stl or use the files from Steve5092's "Mobile Phone Tripod" here https://www.thingiverse.com/thing:2809416 except replace the Ball_Seat.stl with my vw-bug-phone-clamp.stl. You won't need the Tripod_Lags.stl (misspelling of legs I guess) or the tripod_center_joint_seat.stl. It will allow you to use the flower vase area to hold the phone stand.
This combines Steve5092's "Mobile Phone Tripod": https://www.thingiverse.com/thing:2809416 and Grumpy67's "Blue Tooth Mic Mount VW Beetle": https://www.thingiverse.com/thing:2748370 to allow the phone holder to attach to the flower vase hole instead of being a tripod.
Update Aug-12-2019:
Added an stl with all the parts together for easy printing.
