About this 3D model

After slicing this 10cm high column change the extruder temperature in the GCODE file after 10mm travel in the Z axis. Examine the print and determine the best extruder temperature for the filament you are currently using. The printed columns can be stored and used as reminders if the same filament is used in the future. After several statements out of the community indicated that the original file was corrupt I have uploaded another version, hopefully less prone to slicing failures. Please read the comments below and check out Deoryp's remix of the file (http://www.thingiverse.com/thing:211514) to avoid unsatisfactory results.
