Heattower Dremel 3D20

I have been looking for a heattower for the Dremel 3D20 for a long time, trying to figure out how to make one. To spare you that, I will explain it here. I have also uploaded the G-Codes directly for those who just want to download and use it quickly.
It's simple and can be done with the Dremel Digilab 3D Slicer.

### How to modify the G-Code using multiple Temperatures in one file

The steps using the Dremel Digilab 3D Sclicer are described below. Cura with the 3D20 plugin works analogously.
You go to (top left) Extensions > Post Processing > Modify G-Code. Then select "Add a script". If you select "TweakATZ ..." you can specify on the right either via the number of layers or the height in millimetres at which point the temperature should be changed (Do not forget the stand). Enter "Keep value" for "Behavior" and then enter the desired new temperature for "Tweak Extruder 1 Temp". For a complete heattower, simply add as many scripts as you have different temperature levels.
