Butterfly Valve Cap

thingiverse

My wife insisted on butterflies for her valve caps, so here we are with this project. I wouldn't advise doing this with a car, as it could easily become dislodged at high speeds. Print the design flat and without any supports. I used a 0.4mm nozzle when printing and it turned out acceptable, but you'll really need a 0.2mm nozzle to capture all the intricate details. Experimenting with line widths or toggling "detect thin walls" can help get as much detail as possible.
