No I currently don't, but must admit I have totally Cognitive dissonance with regards to them. That is part of me sort of think they're cheating and another part of me really admires what can be done with them and I'm more than happy to buy 3d printed parts (I have currently added parts from 4 different manufacturers on my Mini alone). I'm sure its only a matter of time, but I think my biggest concern is I think my build rate will be even slower. So at the moment I'm more than happy to marvel yours and the others on this forum who have totally mastered it. - PS. The alpine looks flawless.
