    defroster vents

    Has anyone attempted 3D printing defroster vents? I'm kinda in the dark on the technology.

    3D Prints

    Yes, I have printed several items for our vans.

    This was a couple of years ago. The Makerbot 3D printer was OK to learn on but I was not satisfied with the quality of their machine. It was too prone to breakdowns. I learned a lot about 3D printing but do not consider myself an expert. If I get another printer, it won't be a Makerbot that's for sure. The prints were OK but not great. The pic below shows how coarse the print was. There are things you can do to smooth it out after the print.

    The vents I made turned out good enough to use but for the money invested in the printer, I was hoping for better quality. With some extra work after the print, they can be made to look much better and would compare well with original units. It's sure a lot better than a couple of big open holes in the dash that everyone can see when looking at your van.

    Here's a 1st gen brake master cylinder cover. These are less obvious of course than the defroster vents since they are usually under the carpet. You can still see the gaps in the edge of the print but they hold together well. It's made of ABS plastic which resists petroleum products very well.

    I made a few other items also; transmission shift rod bushings and the 2nd gen MC cover. For the items pictured, I'm selling the vents for $30. each and the MC cover for $35. both plus shipping. At that price you can probably get a decent pair of original vents but sometimes those items don't come up when you need them. It would be nice to get back into the 3D printing but I'm not going to buy another $1,000. printer right now, I've got too much else on my "to do" list.

    Thanks 108, that's good to know. My vents are getting crunchier all the time.
