Hatchbox Spool Adapter v2
thingiverse
Multi part 2.15-2.2in spool adapter requires two "hub" parts, one "spacer" part, and two 1/4x5/8x.196in ball bearings, along with some glue for a 1/4in shaft assembly. The space between the hub parts is optional; if your spool fits snugly, you can skip this step.
