Hatchbox Spool Adapter

I didn't like the oversize center hole in the new hatchbox spools so I made an insert for them. The spools aren't all exactly the same size so some fiddling may be required on the model. Let me know if there are changes I can make to make it better. 

The slicer settings I used should upload with the 3mf file. Print flange side down with snug supports at .1mm distance to part. My supports came off in one piece with little effort that way.

Thanks
