While I was looking at oof_32's modified marble race pack, I observed a few errors.
1. Some of the parts were not grouped, so I grouped them.
2. The shooters. The original was all glitchy. So I updated them. But I kept the original because some of you might LIKE these shooters.
3. The rainbow path was missing the original one, so I added that.
4. The gold-silver-bronze indicator was missing the description, so i added that.

I also added new tools! (Most of them I drag and drop)

What's new:
Grouped some of the marble tools.



Thanks to thecoolmarbleraceguy and oof_32 for the marble tools and the modified marble race pack.
