Sample Filament Spool Holder for small and medium winding

Quite a lot of sample filament I have purchased have been quite a small diameter winding so I have found myself having to rewind due to my previously printed spool holders having a too large diameter.

This thing therefore as a small diameter basic spool with an extender and spacers to increase the width and diameter of the spool.

There is no ingenious modular concept at work here. I just needed a flexible spool holder after wrecking some new samples and thought I would use up some end of spools at the same time.

Printed @ 0.2 layer height (spacers 0.3), 5% infill, 2 perimeters and no supports.
