I remixed this two part mount to be a one-part mount for the Galaxy Z Fold 3. It should also work fine with the Fold 2. It fits in the dash cubby hole in my 2015 Kia Optima, and other kia models with the same hole.

It fits the Samsung Aramid case, and should work for most thin cases (including my printed case design). If you find it wont fit yours send me a message on reddit and I'll see what I can do to make it work (/u/4lan9)

I included both portrait and landscape mounts. The portrait one has a hole on the bottom for speaker and charging port, and the landscape one has holes on the left and right for speakers.

The fit is very snug, you may need to sand it to get it to go into the cubby hole.
