Think Universal's Jurassic Park River Adventure™ or Disney's Splash Mountain.  This model of a flume boat is perfect for anyone interested in theme park ride models.  It does take some time to print so I recommend running it overnight.  The supports inside the model to support the railings should be removed gently so that the model itself doesn't break.

There may be a larger model of the ride itself coming in the future, once I have more time.  Hopefully with a working water component.
