This blue prototype was built in the most basic of all layouts.

I typed on that for a month and I don't like how muted the spacebar was so I decided to add some acoustic cut on the spacebar area both on my prototype and the model.

And I ended up infilling the front engraving with acrylic paint.

For the GBrun, there are some changes since the prototype unit, the case wall size has been reduced and the wall that separated the xt column has been thickened a little.
I also added a chamfer all around the bottom case and the seam, and also the plate height from plate to top case has been increased from 7.5mm to 7.8mm.

Anyway here's a sound test of the first build of the prototype unit, without the spacebar cut yet.
