Fixed granite grinder prototype

In my first-day noobishness, I didn't realize that LDD's mode is saved along with the lxf file, which explains why I wasn't in Extended Mode despite switching to that tab before opening my original file.

Well, here is a properly-colored version of the Granite Grinder prototype -- teal parts and dark gray feet. I might try building some completely new vehicles tomorrow. It's been a while since I did anything creative

One of the corrugated pipe pieces doesn't work with the flex tool (doesn't have a flex icon either), and it happens to be the one length I need for this model. The others work fine though. I'll just leave it off for now.
