Simple and secure filament spool - no screws

Made in DiamondAge PLA on an Ultimaker.
Not so long ago I posted http://www.thingiverse.com/thing:179804 which required screws for assembly.
This design is fully printed and is also secure. The assembly is via a pair of pins.
I've posted 2 types of pin. The first is a spring pin (I prefer this one) and the second a star pin.
