In Tinkercad import an svg of your name.
Once imported, you can duplicate the object.
With one of the objects, choose fill mode from the "Shape" dropdown menu and click on "Outer Line" of the object.
Change the "Line Width" to 1 or 2.
Change the "Corners" to round edges.
Change the "Quality" to at least 10 or higher; this will help smooth the edges and make them more round.
This will then create the outline for the name.
Keep the original imported svg of your name as "Default" and taller than the "Outer Line" object for the 3d depth effect.
You may also need to create another duplicate object and use the "Silhouette" fill mode if there are any gaps between the "Default" and "Outer Line" object.
