It works! Had a lot of fun printing this for my first big project!
Used an Afinia H480 printer, all PLA. I had to have the main spring printed by someone else, my printer isn't quite large enough.
Where did you get these extremely hard to find 1.8mm screws from? Did you just use other screws?
I cont find the part number right now, but I got them from www.Grainger.com
