V3 Depending on your extruder there may not be enough clearance for the arm of extruder to move, I left the parts if you can and prefer the narrow version. V3.7 The mounting blocks and the Carriage have been redesigned so there is about 4mm of clearance between extruders, the mount for the cable/drag chain mount was moved forward. The Screw holes for the M4 screws were resized so they go more smoothly into the the linear bearing pillow blocks.
