The stuff they used appears to be zinc-plated mild steel, which can be bent to shape. I recommend bending it with a minimum bend radius = .025 in (half the material thickness). All the pieces are .050 stock except the "panel", which is .032.
Like most metals, you should avoid re-bending as that would weaken it a lot. Most likely you've tried flexing a piece of metal or plastic back and forth to break it off - each time you bend it it weakens it more. This is sometimes called "fatigue".

Should I look in to the extra materials pack? (I heard it's about $70, a little steep for me to just grab..)

Yikes! You're right:
Metal and Hardware Kit $79.99 (- 10% edu. discount) How perplexing!
I'm at about the same point - I've done the Squarebot, chased the dog, started up Easy C and run the Online Code to check out the I/O. Next I think I'm going to look into what speed the Vex should be capable of. I need more speed to keep up with the dog! JVN
posted the approx. speed and torque for the motor which I'll plug into his
Mechanical Design Calculator and see what happens.
