Spool Divider (parametric)

Like anyone else who 3d prints, I have a decent supply of "end of the spool" filament. Y'know, lengths of filament that are too short to trust finishing any decently sized print, but perfect for making smaller parts or adding a dash of color to a larger print. I had many full size spools with such lengths lying around taking up room in my dessicant box.

To save space, I brewed this thing in Freecad 0.17. I had several Hatchbox brand spools with remnants on them which I wanted to use as cores (they are wider than the others so can fit more different colors). So the uploaded STL files fit Hatchbox spools (40mm ID, 100mm OD). There is also my spreadsheet parameterized Freecad 0.17 file if you want to make adjustments to fit other spools.

There are some other spool dividers I've seen in the wild, but most of them lacked either the fit or the features I was after. Besides the obvious need to fit Hatchbox spools, these things also have a starter filament clip near the base and plenty h
