This is Buying, Ordering and Delivery of Ultimaker part of ultimaker forum , where If you have problems, delays and comments about how it works, you can post it and and try to make it work better.
I just shared my experience, and read about others here, and wait for help, and voila, its here, thanks to Sander.
If you dont comment how things are working for you at ultimaker is impossible to improve, and I dont think saying it loud is a bad think.
I am very happy with my printer, I think ultimaker2 is the best out there, but sales had been a problem when I bought it and now with this critical spare part.
I ordered at ebay a replacement, after 10 days waiting for an email from ultimaker saying it has been sent that has not arrive yet, and because I need my printer working, I dont know if it is official or not, They shell it as an ultimaker german teflon coupler, will see if it works.
