About this 3D model

This is a simple small parts tray. I needed one for holding small screws, etc when I disassemble a device. I searched Thingiverse for one, but didn't find one, so I designed this one.This is my very first 3D design. I used Alibre Design to do it. It's very cool to design something (simple or otherwise) from thin air and, a couple of minutes later, be holding it in your hand!
