Heat Tower

I have wanted to run this Temperature Tower on my 3D Printer to see which temperature the different filaments I use print best at, but every file I downloaded showed massive errors when I ran the file(s) thru Autodesk Meshmixer. So, I made my own.

I'm not real great at modifying my own "G" Code yet (or own a copy of Simplify3D). So when I print this "Tower" I just watch for the "Bridges" to print then manually lower the Hotend temperature setting in Repetier.
