Butterfly Valve Cap

My wife wanted butterflies on her valve caps so here we are. I wouldn't recommend this for a car as it might just get flung off at high speeds. Print it laying flat and no supports. I printed with a 0.4mm nozzle and it came out good enough, but you really need a 0.2mm nozzle to capture all the detail. Try adjusting your line widths or toggling "detect thin walls" to get as much detail as possible.
