Uploading a recreation of the CSL flap seal.

There are two versions attached: the first is a 1:1 replica and the second is a slightly modified version so that it can print flat on the bed plate without supports. This should be printed out of some relatively stiff (95A or so) TPU.

Note that you'll need to print two, one for each side of the flap.

See this post to see the print optimized part installed on 0-60motorsports's car: https://nam3forum.com/forums/forum/m...014#post357014

Also, just for reference, here are some pictures of a basically new OE flap:

I installed the 1:1 Version. Im sure it'll hold up just fine and i will give you feedback after the summer. the "real" test LOL. Cheers.

Does anyone have a scan of any flavor of CSL snorkel? I’m working on a snorkel that can interface with the non-CSL bumper brake duct as well as the oem ducting from the kidney grills. Would love to have a reference mesh, it would save me a lot of printing and fit up.

Messy scan of the Karbonius snorkel: https://s.digital3dcloud.com/space/f...8-fad9ae1ec8fa
Karb snorkel in relation to chassis and bumper: https://s.digital3dcloud.com/space/f...0-a67e5041f647

Note that the Karb snorkel is NOT the same as the OE CSL flap. The snout of the snorkel is clocked slightly differently. IIRC, when installed, the end of the Karb snout is ~10mm off of where the OE flap sits. Don't think any of this matters for your purposes, but it's worth pointing out.

Hope those help!
