dual extrusion - step 2

I designed a carriage that supports larger & interchangeable hotends without removing it. essentially a carriage with a big hole in the middle and 4 holes for bolting adapters to it. I adapter the carriage from Thingiverse with the slide on fan shrouds. when I print and test the adapters I will post the whole mess to Thing. restarted this print several times before I realized my issue was from my PLA being too wet. new roll and tweaking steps per mm of the extruder and it looks like I got a good print. 7:40 to print. still using marlin 2.0
