MakerBot Print is our newest print-prepration software, which supports native CAD files and STL assemblies,
allows you to interact with all your printers via the Cloud, and many other exciting new features.
You probably can print it without support. Without support, there might be not a enough of a gap between the pressure points and the ring, and the battery might be difficult to insert and remove.
I haven't tried without support as it isn't a lot to begin with. Make sure to lay it flat so that support is only needed around the ring keeping the pressure tabs in place and inside the clip. Without support, it would probably be just fine.
