Classified Forums - Read this first!

Here's a few simple guidelines for this forum. Failure to follow any of these rules will be grounds for your thread to be closed


Post your information
Post as much info as you can. Say where you are located, where the part is located, the best way to get in contact with you, if you are willing to ship, etc.


Post the items information
Post as much info as you can. A price must be posted, as well as pictures of the item(s). Post as many pictures as you can, even if it is a common item. A picture tells a thousand words, but it can also conceal another thousand. Links to hosted galleries of images are acceptable, links to eBay and/or Craigslist are not. Once the item sells, please do not edit your ad to remove the price. Many people search through old ads to get an idea what their item is worth.


If listing a car
-Post the year and model
-An accurate mileage. If the odometer is broken, post what it is currently at and how many miles you believe it has
-Any aftermarket modifications
-Any known issues or damaged areas
-Post a price
-As many pictures as possible of every area


If listing wheels and/or tires
-Post the brand and model
-Post as many specs as you can, including but not limited to tire size, tread remaining, wheel diameter, width, offset, bolt pattern and centerbore, if multi-piece the lip, barrel and center size. If they have been redrilled post the original bolt pattern and where it was done.
-Any imperfections, including but not limited to curb rash, bends, cracks, repaired areas, scratches. If tires, any gashes, bubbles, cupping and curb rash
-Post a price
-As many pictures as possible of every wheel


If listing Parts
-What brand and what models it can be used on
-An accurate description
-How long it/they have been used for
-Any imperfections
-Post a price
-As many pictures as possible of every area


Miscellaneous items
-A detailed description of the item
-How long it/they were used for
-Any imperfections
-Post a price
-As many pictures as possible of every area


WTB threads
-Be as detailed as possible
-List exactly what you want, what variations you will accept, colors or materials, etc.
-Post what you won't accept. This includes imperfections, colors, models, etc.
-Post what you are willing to pay. Only douchebags will bump up their price if your price is higher then theirs.
-Where you are located and if you would prefer local pickup only


In case the point was not made, everything being sold must include a price and as many pictures as possible.
-This is not eBay or Craigslist. Do not post links to either for your ad. The same goes for other forums. Either post your information here or have your thread closed.
-Feeler threads are not allowed. If you're not sure about selling it, don't post it.
-If listing your item for trade, post what you are looking for, what you feel your item is worth, if you would like cash back or if you have cash to put on top
-Thread crapping is not allowed. If you're not interested in purchasing the item for sale or have nothing positive to add, please stay out of the thread or else be prepared for a time out. If you complain about the time out, it will be extended.
-Only bump your thread once a day. You are allowed to respond to others more then once a day.
-If listing multiple items, post them in one thread. Exceptions are cars and wheels.

              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.
