Summary

This adapter will allow you to wind your 5" Schacht shuttle bobbins on any modern cordless drill.

Print it on its side with a flat side down, and no supports are required. Low to medium infill. It's designed so that it'll have maximum strength when printed on a flat side.

It might work with other bobbins up to 7" in length with a 7.85mm internal diameter as well, though those longer bobbins will stick off the end of the adapter.

Print on its side, one of the two flat sides. This allows the layers to be continuous along the length of the adapter and maximizes strength.
