Dual extruder offset tuning tool
thingiverse
I designed this tool to precisely calibrate dual extruders heads by fine-tuning their tool offset. This design takes inspiration from a discussion on maker forums (link: http://forum.makergear.com/viewtopic.php?f=13&t=2747 ). Below are the instructions. A Vernier scale is employed, where each line signifies a 0.05 mm shift. Print this with two extruders to observe when they align. An exact offset will be revealed as they line up roughly in the middle of the longest line.
