About this 3D model

Very new to 3d printing and this will make my fourth or fifth print apart from very small things. Looking at it, many of you experienced folk are probably shaking your heads but I figure I'm not going to learn unless I jump in and start screwing around. Anyway, I didn't make the 3d model. I found it here http://sketchup.google.com/3dwarehouse/details?mid=6250854ecf2b954269095ca863cece2f&prevstart=0 when I went searching for a Mobius strip to print. This is more interesting than a basic strip and seemed like a good challenge.
