This is a 1:10 scale "toy" H015 Sentry Droid. It's been modified heavily to print OK at 1:10 scale. Most notably the antennae and other thin/tiny details (though the Lego Greeblies on the bottom print OK, so they get to stay).
We build Lego Star Wars droids, so when I learned about H015 in The Force Awakens, we decided to build it. (This was before we'd even seen it - BB-8 was already on our agenda though). You can check out our Lego full-scale build log on RebelDroids.net
For various reasons, the Lego droid has been complicated. Our original plans "skirt" didn't fit around the Lego at the bottom. We know Lego, the Lego was right, so that meant the 3D model needed help.
After carefully reviewing photos taken from Star Wars Celebration: London, we were able to get it figured out - good enough for a toy anyway.
Full disclosure: Gearbest gave me the CR-10 that I printed this with, so I feel sort of obligated to put it through it's paces.

Notes:
The head and antenna could be printed as one, the separate models is a legacy of how I designed the model. However if you break the antennae, they're easier to reprint if they're not on the head. Maybe easier to paint to.
The head & antenna are printed right-side-up. The body is printed upside-down. Supports almost aren't needed, but I used a few:
Around the "neck" in the head I didn't trust it, so I let the slicer add supports there.
Where the neck goes in the head could use support. That area isn't visible though
Around the "waist" of the body (black zig-zag line) each side has a platform that sticks out and could use support when printed upside down.
