Published material guidance; still check heat, UV, load, and printer compatibility.
A planning starting point only; wall count, orientation, and geometry often matter more than infill.
Choose the needed variant, then slice it for grams, cost, and print time.
Saved setup guidance is used for material, infill, support, and per-file recommendation text; editable numbers are planning estimates only.

3DPrintedCarPartDescription
Nissan Leaf's Aerodynamics require a floor of fiberglas below the motor/drivetrain. I was replacing my brake fluid today and dropped the cap down beyond the point of no return. I wasn't going to take the whole bottom off the car just for a little plastic cap. I couldn't find a cap that would fit so I measured it out. 34mm widest point, 28mm cylinder around the top. This is designed to screw onto the existing threads. I found the part for $13 on Nissan's website, but hey, 3D printer. Here's the source model for adjusting: https://www.tinkercad.com/things/7JAe1vDGpbW-brake-fluid-cap/edit My first prototype (that seemed to work after re-shaping), had no grip so I added edges, as well as adjusting the measurements slightly. #Safety Warning It was brought to my attention that brake fluid is very sensitive to moisture. Having just 2-4% H2O moisture in fluid changes the freezing and boiling temperature of the fluid. See moisture related brake failures, I recommend spraying the underside of the cap with Flex Seal or another alternative that gives the cap a water tight seal when twisted tight. Anybody who has printed a cup should know prints can't hold out any kind of liquid. Don't run this cap for more than a few days without some sort of seal. This would be a great temporary cap but shouldn't be trusted for long term use.
