This temp tower will start at 230 degrees Celsius and will end at 190 degrees. It's better to print with a higher temperature at beginning and go lower. 

I added a new file with temperature from 230 to 200 degrees. 

You can use this file to identify the best printing temperature for your filament. 

I scaled the original version from Skandberg777 to 80% and modified the gcode for better results

The filament in the picture is Prusament Galaxy Black.
