About this model

This is a Sentry Droid - a "floating ball" that can be friend or foe. It prints in 2 halves supportless that glue together (with an alignment pin), or a single piece that requires support. You can use a clear acrylic stand (like those from LITKO) for this, or print one of the free ones I released previously.
