If you happen to be dumb like me and clean the nozzle with the machine on and blow one of this little things and own a Workhorse theres 5 spare inside the unit. I blew one today from my own stupidity on my TAZ 6, when I was on the phone with Lulzbot asking if I could get some overnighted, I had said I also have 2 TAZ Workhorse’s. They said inside the case above the board there are 5 spare can take one for the TAZ 6. here’s what the look like. The TAZ 6 has 2 of them and they are tiny. 4/16thx 1/16th
