What 3D printing material to use for object inside a car? Temperature test

Title: What 3D printing material to use for object inside a car? Temperature test. Watch on youtube:

Tags: 3dprint, temperature test, inside car,

Few times I wanted to 3D print an object which will be inside my car, but I was not sure which material to use. On internet there are so different information, but they must be different, depend where the author lives. So, I decided to do my own test with 7 materials. On test probes I placed M10 screw nut, just to add minimal load to objects. I chose 10 very hot days in a row, during this test, I always placed my car on hottest sun, turned to the South, but since here in Budapest (45° latitude) summer is not too hot, last part of the test is simulating higher temperatures in oven.
