@Daniel_Noree I had a little problem when printing the Center Diff, could you send me (or publish) just the two little parts like on the picture? It would be so nice so I don’t have to print everything again (took almost 2 hours) 
Sure I will do it as soon as when I’m at my computer. Will be a few hours though I’m afraid…
@Pascal_POECK Here´s the link: https://docs.google.com/file/d/0B7TCLh-I8q6YSzJmaU9TVDB5TGM/edit?usp=sharing Let me know how it works out!
Btw, those are slightly longer than the previous ones…
Waouw that was fast… I’m busy with a 3 hours print so I’ll do this one next monday (leaving to Paris for the week-end) but will keep you in touch 
Thanks again
Done, excellent. Thank’s again
