I ran a 3d printed rain hood this weekend. Worked pretty well.
Saw on FB where someone was 3D printing their own conical washers for seat and floorpan mounting… Neat idea that opens up some options for color matching…
My son is replacing his purchased rain hood with a 3D printed one he is designing.
Wish we had them this weekend. Broke his prototype just before we left and didn’t have time to print another. With the high speed track and very high air temps I think we could have benefited from being able to start 1 psi higher (which our previous testing there had shown us). Average lap speed was 57-58 mph and they were loading the heck out of the right rear.
End of the day we were punted 3 of 5 sessions (penalties issued for all 3). So maybe the fans wouldn’t have helped that much. 
Fertile soil for another 3D print project….
Some 9F wheels may solve most of your problems!
90 degree ambient, super high grip, longggg corners at Quaker City last weekend and the 9Fs kept the tire temp steady for our nearly 20 minute final.
What wheels were you on Chuck?
Diverging from the 3D print a moment. We were running stock CRGs. Having to start down 8-9 psi especially on the RR. I think there could be benefit from being able to start a long final higher than everyone else. But maybe the dumb engineer is overthinking it.

Stocking up on parts. My goal with the long weekend is to get some beauty pics done and getting them all listed on the website.

TKART wrote an article about the LG COOLER 6.01. The product promises up to 20% reduction in brake disk temperature.
Not sure if I’m allowed to post it here because it’s technically behind a paywall…
The complete LG Cooler installation procedure
I may or may not give this a try in an unnamed CAD tool to perhaps 3D print a variation of this which will not have a specific name or be sold to anyone if it’s viable to create at all… 
Might want to give some other brake disk cooling prototypes a chance as well when I’m at it
Seems like an expensive axle to have to replace when I inevitably bend it 
You’ll want it printed in metal so you get the heat transfer. Plastic won’t cut it. So unless you’ve got a $50k-$200k printer this ain’t going to be worth the effort.
Meh, the metal is just a heat sink anyhow. Put a plastic fan at the END of the axle, and 2nd fan with same orientation at other end, and just rely on the airflow. I’m not convinced it will be measurable, but who knows…
Even if you packed the axle with ice, I doubt the rotor would have any measurable difference in temperature.

Well then you’re just blowing air down the axle with virtually zero heat transfer
I think the point of the metal version in conductive cooling to the insert then convection cooling with the added surface area doing its thing.
What about pedal extensions? Has anyone made a set?
I Mychron 6 Sunshield would be nice…
Can’t be that hard right, what are your expectations?
Does anyone have files of arai GP PEd the spoiler and the chin one?
Which filament have you used to print the chassis protectors? TPU, PETG?
