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.

$\begingroup$ I managed to download the file as a .DXF. Will that open in AutoCAD? $\endgroup$ – tdrsam Apr 8 '16 at 0:30

$\begingroup$ It should, as well as open in many other CAD type programs. DXF means drawing exchange format. $\endgroup$ – fred_dot_u Apr 8 '16 at 14:00

There are solutions with instant delivery/conversion, and others that take some hours to send you the file. I found solutions varying from free online conversion to pricey service. You may need to do some touch up on the files converted from automated platform before you send it to a CNC or other CAD/CAM machine. You can check on these platforms: http://cadmesh.com https://www.convertcadfiles.com/
Have in mind that, the higher is the model complexity (shape) the harder is to convert the model. If trying to convert a 3D scanned model, make sure to have a closed mesh and a high-density mesh definition. Good luck!
