Click on the

Scale

button to

access the scaling controls. As you
can see, I changed the value to .75
or 75% of its original size. Click on
the small up arrow next to the

Save

button at the bottom of the window.
This will allow you to save the object
under a different name if you don't
want to over-write the original.

Before we start this print, let's take a second to examine a feature of MatterControl – the

Layer View

. If you've not sliced this object yet, you'll like see the text “Press 'generate' to view

layers”. Go ahead and do that now.
