 Maybe this has a function for someone as well. Could be useful in some situations, but I don't know. (Free real estate ;-))
+I designed (a bit over an hour) and printed (2:38 h) the case for my test board. It screws together with M4 bolts and threads itself into the plastic. Because I made the holes for the jumper wires a bit too small on the outer edges, so I decided to solder some wires in place. I didn´t do a great job but I works for now and it looks a bit neater on the outside.

+Fortunately, even the keys fit perfectly the first time. I found this document where everything about the position of holes for the switches and distances between the PCB and the switch itself is described (in inches but fusion converted them perfectly): {{https://datasheet.octopart.com/MX1A-11NW-Cherry-datasheet-34676.pdf|MX Series - Desktop Profile 0.60 Inch Keyswitches}}
+I then soldered and assembled everything and this is what came out:

+I didn't put in any metallic foil right now. In the first test, it seems the noise/interference is a bit reduced, but the plastic housing really didn't help a lot. When I hold it midair there is still a difference in the readout when I put my finger on the back of the case. Next, I will try to put aluminum foil on the bottom of the case.
