Copying/pasting objects

[Nismo370z]

I have two small objects that I've imported into a new project. Is there a simple way for me to copy and paste these objects if I wanted to duplicate/print a lot more of them on the same print or do I have to manually import more?

Yes, there certainly is an easier way!
