Fire Extinguisher Pin and Quick Release Cap

Ever wondered why the pin on fire extinguishers are basically zip tied on? How hard is it to break in case I need the fire extinguisher in an emergency? Well I tried it and while it certainly is not extremely difficult, it was harder than it should be. So I designed a printable pin with a friction fit cap that is snug enough to keep the pin in place, but still pops off easily when you pull the pin. One side of the pin is flat to make it print easier. The cap also fits metal fire extinguisher pins.
