N0SA Keyer Top Cover

The N0SA keyer is a great keyer for SOTA/POTA activations.  In inclement weather, the skeletonized design will allow debris/rain/etc to interact with the contact surfaces.  Additionally, depending on the setup, one may feel the heat off the keyer pins.  This top cover design can mitigate those issues.  The existing screws are used to secure the cover in place.  I recommend printing with PETG in particular for extra strength for the thin, front partitions.
