Making 3D models of bike parts

I've been performing more monotonous functions at work lately so I decided to try and model some bike parts in Pro/ENGINEER. I am putting together an interior gear rack for my Xterra to hold a mountain bike as well as my other riding gear. Some of these parts will have to be fabricated and I figured I could model them up just to see how they would look before cutting anything. I want to incorporate some water bottle holding features So I modeled these versions up and rendered them just for fun.

I'll post more pics as I get further along.
