Parametric ergonomic support with wrist rest for Apple Magic Trackpad
This model is based on 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.com/thing:2205899
