Looking for Suunto d6i Replacement Part

[cleomagic]

We have a Suunto d6i. On a recent dive trip, the silver side cover over the pressure/depth sensor disappeared. (This is the side opposite the computer interface.) Not sure what this is called, nor where to find one (along with the screws). Haven't gotten around to contacting Suunto directly but hoping for a more cost-effective solution. The attached picture shows the part we are looking for.

Thanks in advance.
