Made this for a friend of mine, it worked well enough for him so I figured I'd post it to see if anyone else could get use from it. The type of switch used is pictured as well. He printed in PLA, but only time will tell with it being used in an automotive setting. I'd suggest using ABS. I'm also going to shamelessly promoto Sunlu since I'm an affiliate. If you'd like to save some cash....and help out a fellow tinkerer, I'd appreciate it!
