Woven Ribbon Tape Spool

My wife was searching for a spool for her woven ribbon tapes. I designed this one.
It fits on a 8mm rod. You can print it in two parts, so there is no need for support material.
There is a gap within the spool, where the tape should fit in to fix it to the spool.

Then cut a M3 thread into the hole and get the parts together with a grub srew as shown on the photo.
