Customizable Simple Pulley/Gear

There are many great pulley/gear customizers at Thingiverse.
However, I wanted pulley customized using similar parameters like customized belt (http://www.thingiverse.com/thing:1529638) to fit together.
Therefore I've created one.
You can configure size, teeth, rim, lock and joint.
