Samsung S6 QI Car Dock
Print in one piece with the large flat side against your print bed.
There are some small chamfered overhangs in this print and some small bridges.
The snap fits worked perfect on my printer. But snap fits are pretty high tolerance. You may need to adjust your post processing or file to fit.
You will also need:
Suction base off a generic car holder with 4 claw type connection.
See photos attached.
Suction base I used (stiffer than the swan neck I used before)
