As requested in the previous post, I have conducted the same test using same color (white).

1.PLA - Hatchbox - White - Printed in Mk3s 2.PLA - Bambu Lab Basic - White - Printed in A1 Mini default profile 

Previous post for reference
First, let me clarify something: I knew it wasn’t a 100% fair comparison between green and white at first. However, I posted the video to highlight the huge difference I observed, which surprised me. I knew the color wasn’t the only factor, though it does play a role. I've printed many Hatchbox filaments in green, orange, and black, all of which were tested for AC vent clips. Thats why i end up using white . It performed slightly better, but not as significantly as yesterday's test. As seen in the video with the thermometer, the temperature difference around 4c, but overall it was a valuable test.

For first clip inside the car as you can see the the middle sample already soft check the lips of the clips dropped, i couldn’t do the test inside the car it was really hot with naked hand

So i left it to cool till around 76 c then tested

For the previous post, the majority of comments were about the color, which is a valid point. However, there are two comments I suggest giving a look at:

• by u/ensoniq2k ( PLA can be annealed to improve its heat resistance )

• by u/thekakester( Additives in PLA filaments, such as color pigments, plasticizers, stabilizers, and flow enhancers, can change thermal properties. )

Additional info:

1. The white PLA Hatchbox piece has been inside the car for 8 months.
2. The white PLA Hatchbox piece was printed on an Mk3s default profile, which is three times slower than the A1 Mini.
3. The white and green Bambu Basic filaments were printed on an A1 Mini default profile

1. PLA - Hatchbox - White - Printed in Mk3s 2. PLA - Bambu Lab Basic - Green - Printed in A1 Mini factory profile 

I have tested this white PLA from Hatchbox for over eight months on its AC vent clips, and it’s still serving well. There are no issues under the sun, just a bit of looseness after 3-4 months. However, I conducted an experiment yesterday; the new green part fell apart after just one day, which is a normal thing for PLA. You might ask, “Why are you printing in PLA?” I’m aware that ASA would be preferable here, but I don’t have ASA and decided to give PLA a shot as a temporary solution. I know color matters here, but still, it was a surprising performance by Hatchbox.
