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. Assembly 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. Also I uploaded the same file twice with different names. I have now uploaded the power_bands_dual_extrusion.stl correctly.
All Happy faces are the same size so they can be swapped around. Ya know, just in case you want EVIL SUNSHINE Happy Face:-)
Printer Brand: RepRap

Good idea to use a skirt for the eyes if printing separately for single extrusion set up.
