Thanks very much, Neg...
Yeah, the 3D modeling process is quite fascinating. When I first started working with 3D printers and designs several years ago, I was surprised at how I had to change my design thinking. There are things that you can do with an FDM process that simply can't be done any other way, and realizing that kind of explodes your head a bit when you try to wrap your brain around it.
If you have any "maker bones" at all, I can't recommend enough that you get your hands on a printer and fiddle with it.... VERY very cool...
