Can someone please assist with the Mini 2 aerostruder idler spring specification. My spring has gone missing and I can’t seem to find the specs for it anywhere and it also does not seem to be available as a part to purchase on any of the normal sites. Please help!! 
It looks like still a current part - try contacting Lulzbot directly - not all of their parts are listed (I wanted a spare build plate complete with the PEI surface stuck on it and they had them in stock, just not on the web site) - they might just put one in the mail - cost more to take your CC# than the spring cost
