Colour change!!
I printed a test card, on a cold winters morning i held it and it stayed grey, a co-worker holds it for a mere few seconds and it turned white. Was i the one with cold hands? turned out yes, i had cold hands and they had warm digits. Being ABS its a bit more selective when printed but turned out great. Now to print a figure or such and tell my workplace that if it turns white i can't work due to being too hot :) Its change temp is about 30C .. hehehe.
