Oh NO! Cosmos and Chaos have informed me that I have released too many Happy Faces into the universe and that I must redress the balance. Hence I have created "Evil Happy Face". To make extra sure it's working, I've given him a "power radiation" base to sit in.

Let's hope it works:-) Because this is it - no more Happy Faces:-P

Files are provided for single and dual extrusion. Application should be fairly obvious. Only thing I will add is that if you are printing power_radiation_base.stl on a single extrusion setup, then you will need to look at your sliced model to work out where the "bands" start and pause your print and swap out the filament.

WARNING: My dual extrusion system is in bits at the moment, so those files have not been tested.
