Prints in two parts. They are joined by 2 M2 8mm socket cap screws. The holes printed tight on my printer, so I just threaded them into the plastic. If they are loose, you might need longer screws and some nuts.
The ears are critical to the design, but it can't hear you. Feel free to tell it all your secrets.
I soldered the shield together, and I cut off the excess pins on the bottom. If you want the pins to stay long, you will need to edit the file.
