Shawn's 3D Model of H015 Sentry Droid67 viewsThis is a fairly accurate 3D model of the outer shell of the sentry droid. It is provided in several formats.

Additionally, there's a "flat" PDF (& cdr) of the panels which can be printed at 100%. Note, however, that the panels are the front faces and don't account for the depth of whatever material you might cut, so you'll either need to cut them a hair smaller, or sand/fill, etc. if you try to use those to build a model.

The "skirt" fits over the Lego greeblies in this version.
