At the bottom of the photo, there are two wrist rests I built out of some spare wood and a wrist rest off of Amazon that I cut in half with a saw and then stitched/glued closed so it doesn't look like hell.

The keyboard halves are stuck to some phone stands using an adhesive Magsafe ring, and the stands are stuck down to the black steel plate with some flat magnets and grippy silicone. The entire thing breaks down in seconds and I can store it to bring to the office. The steel plate is the most annoying thing to transport.

Happy to answer other questions!
