I just had it set to "fine", which makes it large because of the curves. The original version was rough. I'm not convinced that there is actually a difference, even with an industrial printer like I use, but I figured you guys might appreciate it if you wanted to modify the STL files.
I think Solidworks also handles STL files poorly, I've had relatively simple parts that ended up being like 250mb.
If it's a problem, I can work on getting a smaller rough version uploaded tomorrow.
