As 3d printing technology gets better, so does the surface finish of our parts. Our second run of 68-70 AMX/Javelin vents have received a tremendous boost in appearance compared to our first run back in 2022.

With car show season around the corner, now's the time to order a pair - https://www.etsy.com/listing/4381009184/ac-vent-flaps-fits-1968-1970-amc

*1971-1974 Javelin/AMX Vents - Economy Option*
Since I started making these A/C vents back in 2021, costs have gone up, so I wanted to offer a more affordable option. If you just need reliable vents and aren’t worried about a factory-perfect look, I’m now offering an Economy version!

The housings will be printed with a different process/material that’s still durable, just with a more utilitarian finish. You’ll notice a few more layer lines, softer details, and small geometry differences compared to the premium vents

These vents can now be ordered on Etsy - https://www.etsy.com/listing/4452232160/ac-vent-flap-set-fits-1971-1974?ref=listings_manager_grid

3d printed Javelin A/C vents are available for purchase! These are printed with an industrial-grade nylon material that offers heat, moisture, and mild chemical resistance. While great care was taken to match the OEM vents as close as possible, due to the nature of 3d printing, there will be slight differences in color and surface finish.

The lead time is 2-3 weeks (including shipping) from the date of payment received.

Hi Everyone! I know i’ve been quiet for a while, but I’m back with a new part! These are the breakaway mirror clips for the 84-96 Jeep Cherokee & 84-92 Comanche that often crack and break. These are printed using ASA plastic blended with glass fibers for a strong, UV and water-resistant part.

**These are NOT copies of the designs currently on Etsy/eBay/Amazon/Thingiverse/etc. I have created my own CAD models measured from the stock/aftermarket clips and further optimized for 3d printing**.

There are two versions available, one for OEM mirrors and one for the Chinese aftermarket mirrors, there are some differences between the two. If you are unsure about which mirrors your Jeep has, a very easy way to tell is that the OEM mirrors have a black cup that goes behind the mirror glass and comes over the lip of the mirror housing opening, the aftermarkets do not have this extra piece.

The price is $19 per pair plus shipping and a small PayPal fee. Parts are printed on demand and will ship within 2-3 days of ordering. if you are interested please send me a PM and I'll be happy to help you out!

*PSA* - I discovered an account on Instagram under the name of amc_automotive_parts_ who stole a photo/description for my 3d printed 71-74 vents and tried selling them. The account is now gone, but it will only be a matter of time before another pops up. Please don't send $$ to anyone claiming to sell the parts that I produce, I will never sell any of my parts via a non-High Octane Design Co. page.
