Download the file and navigate to Simplify3D by picking Tools, then Options, and finally Machine from the drop-down menu. At the bottom of this window, select ADD and browse to the location where you downloaded the file, choosing it once found. Click OK to add the build plate to your desktop. This step isn't required but helps you visualize the part's position relative to the table by making it easier to see.
