filament spool (flexible width, fast print!)

The priority for me was to make a filament spool, which printed quick, and had a flexible width. This is it. It works great for me.

If you, like me, use OnShape, feel free to customise the design, should it not fit your needs. You'll find the design here: https://cad.onshape.com/documents/e7f5f21d92d44a418f3e0aee/w/53cd1dda6d604ed793e7a620/e/71dab07eab6548af80275582
