Spool stacker

Description

I haven't done much electronics projects in a while, but I still have boxes full of components and wires. I started organizing the workspace, and while untangling my box of small wires I decided to make something to organize the wires a bit better.
My first idea was to use cut pieces of cardboard tube from a toilet roll as the hub for a spool and 3d print end caps, but my plan changed when i was designing the caps
I changed the design to sort of a stackable spool, printable without support
After a bit of testing | ended up with a pretty usable design.
My first design was a simple flange with a simple lip that snapped into a groove. Problems with that design were that if I rolled the wire too tight it released the next segment. And it was a bit to flimsy. I made it a bit thicker and decided to add a little extra rim to support the next spool better, which also keeps the wires on better if the stack separates. The spools rotate freely, and a cap finishes a stack
