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 added an additional platform 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.
