Hi there!

I've had my PrintrBot Play for about a week now, and have gotten it set up to the point where I can successfully print things I download that others have made. However, I'm having trouble with my current print that I built myself. I'm using Cura to print things, if it makes a difference.

My printer keeps building support structures inside where the empty space should be. On top of that, it prints 2 separate pieces for some reason that never come together. I've also seen some corners curl, but I can deal with that separately. I'm just curious if there is something in my STL that's causing it to mess up the print. I've run the STL through netfabb basic to check for errors and had it repaired, but nothing has changed. I've included the STL file for reference.

Any help would be appreciated!
