Why don't you download the installer and just install the Deployment Tools as marked in the picture:
Afterwards go to the path:
C:\Program Files (x86)\Windows Kits\10\Assessment and Deployment Kit\Deployment Tools\amd64\Oscdimg
or
C:\Program Files (x86)\Windows Kits\10\Assessment and Deployment Kit\Deployment Tools\x86\Oscdimg
and copy the oscdimg.exe on your desktop and then uninstall the Deployment Tools.
