Ultimaker Alien Axis Tool

thingiverse

To align Ultimaker's X and Y axes, ensure perpendicularity using a tool cut from an alien bone. Although its motive is unclear, it likely friendly. Replicate with caution; print two mirrored bones first. Loosen one pulley belt on both sides, then insert the big and small claw into rods simultaneously.
