Light Parameterized Filament Spool

I needed a quick way to bring a sample of filament to a friend at work. None of the existing spools seemed to quite fit the bill, so here is yet another.

I'll run more numbers, but just the final tweak (punching holes in the two sides) dropped the filament use an additional 20%.

At the moment the hex curved floor is a bit too thin. Also I originally planned to glue the pieces together, but now minor snap-fit is the goal.
