Vex Crank

I created a custom Vex Crank. We ran out of these little handles. I used Autodesk Inventor for my first draft and switched over to 123D. After about 5 prints and tests I got this to just the right size. The handle is study enough to hold and the hole is the perfect square for the shaft. I had a lot of difficulty finding a printable one so I thought I would share.
