Overview

The adhesive used to keep cardboard spools together isn't rated to go above 50C, so for peace of mind when drying and/or just using cardboard spools, I created this brace.

After printing, you'll want to screw the parts together and apart a few times to make the threads wear in.

Also, incase it isn't obvious, you'll want to print this in a fairly high temp resistant material like ABS/ASA/PC or it'll also melt like the glue when you're drying the spools

Known to work with the following spools:

1. CatYarn (duh)
2. Overture
3. Sparta3D
