The Prototype has issues getting the components to fit cleanly. This is a side effect of the solid body construction, and I have an elegant solution. I will call it the Lock Block.

On the left side of the chassis there is a set-screw that will push the orange block to the right, acting as a clamp to hold the keyboard in place. 

On the right side of the trackpad there is a similar solution.

I also fixed the modular mounting holes, and eased up on device tolerance a bit.

I am going to print this "upright," so the peripheral channels on the right and left side can print cleanly without any support.

Let's try another print!

Let's see!
