Small Wire Spool

A friend needed some simple, small, cheap spools that fitted in with the others he had for wire wrap wire. Lots of it.

Internal/usable dimensions: 30mm core. 20mm depth, 23mm width.
Two holes on each side for start/end.
The larger one has a final internal width of 36mm, hopefully.

EDIT: I would not recommend it for something like filament, it's for thin stuff. Like wire or thread.
