Get Ultimaker kit on the 11th, on the 13th during build discover teflon plug end for the Bowden tube is missing, search everywhere several times, wonder if this part is not obsolete 'cause wiki doesn't get updated very fast I notice.
Post on forum, told I definetley do need piece, so then after exploring all these avenues contact Ultimaker, get a vague non committal mail asking have I perhaps "misplaced" piece myself , if not, mail back and they will sort it out for me.
Mail back assuring them that I have most defineltey not "misplaced" part and explain other avenues taken before contacting
