Figure 5.18 The Hello World medallion printing properly.
Notice in the photos that I've put down a wide strip of blue painter's tape on the
print bed as I wrote about at the beginning of the chapter. I did this before the print
job began (and before I turned on the heat). Don't forget the painter's tape—it will
help you remove the finished print job—you don't want the hot plastic stuck to the
wooden print bed! Just peel the tape off the print bed when the print job is done,
and your printed object should pop off the tape easily. You can see the finished
medallion (before removing from tape) in Figure 5.19 .
