Scratch the Cat badges for my Code Club attendees. There are a few already on

Thingiverse but none with the requisite layers to get the result I wanted.

It takes four colour changes to get the desired effect but the end result is quite

good.

I advise that if you wish to scale this, that you do so only in the 'x' and 'y' axes.

This is so that you maintain the levels needed to implement the necessary colour

changes. Of course, if you have MM then you can simply flatten the model and use

that.

I've included the SketchUp file for Tinkerers.
