These look like really cool pieces! For your purposes as a bowling alley gutter, though, the studs will be in the way, causing the ball to bounce back on track as opposed to falling into the gutter. I'd suggest a different design much like the new 1x1 45deg. slopes that have a 1x1 plate sticking out the back:
That way you can still have your curve, but you can also have a flat tile leading up to it.
Also, every piece looks like something LEGO would create except for the outside curve with one stud on top - the top curve comes WAY to close to the stud, I don't think TLG would approve a design like that - they'd be more apt to do away with the stud in that case, I think.
Thanks for nice comment and suggestion. I find that to build a bowling lane or a pinball floor. It is better(flatter) to use side of normal bricks instade of use tiles. For gutters use new curve roof tile and invert curve roof tile to become SNOT and very realistic in looks and functions.
The outside curve with one stud on top, I notice that the stud is not complete, too. The stud design can be same as stud of a 2x2 round plate or 2x2 round brick.

This looks really professional, bbqqq!
I really love marble runs, I will have an eye on your project.
And I keep my fingers crossed for the unlikely that TLG will produce these great bricks sometime.

Thanks, I interested in solid modeling, Love marble runs, too.

I will design some more soon.
