The case I used got warped in the car because it was too hot. Originally I just took the tablet out when I parked at work because I didn't want it baking in the sun. But taking it out caused the curved parts to widen. I had to find another alternative that was aesthetically pleasing.
I used

The clip on the weights can be unscrewed. The curved part that clips in there, I cut off and sanded it down enough so it was flat enough to gorilla glue. I then went through several annoying steps to make it look pleasing to my eye... In the end, I like how it came out. It clips in and even has that lock switch so it can't be easily pulled out. It's a very firm fit and I can now remove the tablet with the case while only leaving the clip in there. No more heat damage!
