Summary

This is a printable spool for the small roles of fillament that you have.
You just have to print(no support needed):
the base,
as many dividers you need to separate the fillament roles and to fill the base,
the top that keeps everything together.
You need also 4*4mm screws or some glue to make sure that the deviders stay in place.

It is 60mm in depth so it should fit most printers' spool holder
