I can download a file from Tinkercad as any of these:
.STL .OBJ .X3D .VRML
Is there a way to convert any of those file types to .DWG?

I found this site and tested it a moment ago. I uploaded a simple .STL file (crystal) and had to register as a user (free, unremarkable) in order to perform the conversion.

The downloaded file was in .DWG format and opened without a problem in AutoCAD 2013 as a 3d object.
Note the placement of the pivot point in Meshmixer (first image) and the corresponding location in AutoCAD.
