About this 3D model

This is a display stand for prop/novelty Jurassic Park DNA sample bottles. My wife bought these for me and I didn't have a good way to display them, so I designed this simple stand. The holes are set to 31mm, and the model could be scaled up or down to hold other cylindrical objects. The model will not stand on its own when empty, but is very stable once the bottles are in there. I used a little bit of double-sided tape to keep the bottles from sliding out of the holder if it's bumped.
