              As I posted on FB, unless these are printed with nylon at a huge temp, they will become limp little dicks in the heat of the sun. I assume it's ABS you printed with by the surface finish I see. So yea....

              Call me an ass, but when I see a bad idea, I have to call it out. This is a bad idea. Interior car temps things need to withstand 240F - as most dash temps get that high. - and of course, 3d printed plastic that is ABS type will be gooey at that point.

                I agree material choice is important here.

                240F is pushing it a bit, you'll need a 100F+ day to get near 200F on a dash. Considering these clips are on the backside of a tweeter cover, it will likely experience much less.

                ABS is likely sufficient, although cutting it close at a 195f-210f glass transition temperature (mushy temp).

                Polycarbonate would be the best filament to use, however its likely going to require a new hot-end for the OP.

                Another option is to make an inverse mold and casting using a high temp resin mix.

                Lets hope these aren't being made with PLA.

                  Thanks for the constructive criticism graves, I'm already aware that temps are something to consider, and mentioned it in an earlier post in this thread, but I appreciate the analogy lol

                  I am printing with ECO-ABS, which I think will be more than sufficient. However I'll look into polycarbonate and see if my printer can handle it.

                  Interesting resin mold idea, I might try that!

                  You're absolutely right that a car is not going to get anywhere near 240F. And especially the area where the pins are, which is enclosed and shielded from the sun.

                  If anyone purchases a set and has any issues (aside from installing them incorrectly), I will be more than happy to completely refund you, or work with you to resolve them, if you prefer.

                    Install tip: make sure all broken off bits are removed from the rubber pockets prior to inserting new pins.

                          I'd like a set of these, but I also need one of the spring clips. Happen to have one?

                            Thanks for the interest and yes I do have a metal spring clip!

                            I'm actually exploring some more robust materials, although we haven't had any issues yet, but I want to make them as strong as possible.

                            Can I get back to you in a week or 2 when I have this new material available?

                              Certainly, I'm not really in any rush, just wanting to get them installed and off the parts shelves.
