This upright bass was originally modeled by ArgDig on the SketchUp Warehouse.  I removed the character he had playing the bass because it didn't look that good and I wanted a model of just the base.  This model looks much better when the edges are outlined as they are in SketchUp and Shape.  Unfortunately the 3DVIA model player does not have an edge outline mode, but you can imagine what it would look like by cycling through the other shaders.
