Noisy Cricket Solid Body

When I first printed the original Noisy Cricket model I noticed that the vent holes were very thin and fragile so I made the body solid in order to strengthen the model. I also filled in the big circular holes near the back end of the Cricket so that they can print fine without supports, every time I tried printing it before it was either impossible to remove the supports without mangling the plastic or it made a big stringy mess without supports.
