The first test on the 3d printed keyboard mount has been successful. Apart from one of the posts breaking because that part of the print came of the bed, all the posts fit their respective hole on the keyboard PCB.

Like we say sometimes at work: "Very good fit! Even looks like it was designed."

Now I can reinforce the bottom of the posts with a wider cylinder, which will also support the weight of the keyboard, which seems to have a hefty metal plate on the front.

Meanwhile, I started working on the raspberry pi fit was well.

Two USB ports will be available on the side, while two will be used internally in the deck. Probably I will also have to add a USB hub.
