DRAFT: Cutter disc for ELAV robotic lawn mower (OpenSCAD)

ONLY A DRAFT - NEVER PRINTED!

This is an attempt to design 3D printable parts that can be used with motors available from the shop I work in (easy for me to get, and cheap too)

UPDATED to fit this motor:

I've tried to make all measurements easily changeable, so with a few changes the disc will fit your motor shaft.
