Miata Intake Vacuum Port Plug

I have designed a simple plug for the intake vacuum port(s) of a Mazda Miata MX-5

Nice and snug fit.

It is important to print this in a flexible filament with good heat and chemical resistance.

Print it slowly for best layer adhesion.

Strenght - only walls, no infill, just 999 walls

Bottom/Top surface pattern - Archimedean chords, not neccessary, but gives it a nice look

Tested on my stock NA 1.6 for 20+ hours of run time, half of which was highway driving. Plugs held up nicely to the engine bay and intake manifold/throttle body temperatures - no leaks, splits, softening, etc.
