Ycarriage x3

need to replace the stock y carriage since i printed http://www.thingiverse.com/thing:235019 's two piece carriage in really crappy pla. will print it once my hotend arrives... figured i'd share + props to wired1 for teh great parts.
Edit1 made it printable with a bunch of editing.(updated file)
update1 finally printed it. will do one more update on this with a new model.
update2 decided to give up the remix and design my own. had to build up to this point and should be able to get a more stable print of the final carriage when its done. edge's were a pain with a 8x8pcb on 14x16 glass. moved to nichrome.
update3 still working on a new bed, well more like aa whole new printer but figured i'd update the x carriage for two 3mm e3d v6's, still gonna be different.
