Parametric ergonomic support with wrist rest for Apple Magic Trackpad

This model is based on [ex-nerd](http://www.thingiverse.com/ex-nerd)'s parametric ergonomic support for Apple Magic Trackpad, which allows the trackpad to be used at an angle.

I extended the platform to provide space to rest your wrist on. The length of the wrist rest is adjustable from 0 to 12cm. You can also customize the angle and handedness as in the original model.

If you're looking for a similar thing for the Magic Trackpad 2, I have a work in progress here: http://www.thingiverse
