Magnadoogle Circle tool

This is a replacement part for my daughters magnadoodle sketching toy. There are two version of this THING. Version 2: is a simple one piece print on makerbot rep1, but was not accepted by my daughter due to the handle looking funny. Version3 is a two part print with the handle very closely matching the original toys shape and size. Daughter liked this one.
This is a work in progress and i have been asked to make other tools a shapes for this toy. so more likely on the way.
