FLSUN I3 X Wheel Carriage

thingiverse

I reworked this from the original part because after a few prints, the carriage started bobbing up and down. So, I moved the wheel holes inwards by 1mm and beefed up the mounting holes for a snugger fit. I also merged it with the print head mount piece, which keeps the print head from jutting out so far and eliminates most of the excess plastic. This makes the carriage much less front-heavy. It still has very little play for me, even after printing with Armadillo nylon alternative filament, which seems incredibly robust.
