Better temperature tower 240-180

GCODE file for printing the "Better temperature tower" from Thump2010 for temperatures from 240 - 180 C on a Prusa i3 MK2 Multimaterial printer (using PLA in the first extruder).
Sliced in Slic3r Prusa Edition (1.37.1). Manually modified temperature settings for each of the segments in the tower as I could not get the Perl script to work:

layer 45, M104 S235
layer 81, M104 S230;
layer 116, M104 S225
layer 151, M104 S220
layer 186, M104 S215
layer 221, M104 S210
layer 256, M104 S205
layer 291, M104 S200
layer 326, M104 S195
layer 361, M104 S190
layer 396, M104 S185
layer 431, M104 S180
