wire length on spool


Hi solidworks user forum,

I am trying to model a custom wire spool used for fiber spooling.

I know the length that I'm after which is 5000meters and I'm using a .25mm fiber diameter.

What I'm trying to do is figure out the height and the total outside diamter if I start with a 25.4mm inside diameter.

Any suggestions.

Attached is my first attempt which represents two turns.
