Alti-2 Neptune 2 Battery Plate

This is a model of the battery retention plate for the Alti-2 Neptune 2 skydiving altimeter.

The original model can be found here: ( https://www.thingiverse.com/thing:863355 ) however, that model didn't have the groove for the o-ring seal and a few dimensions were off. I corrected most of the dimensions for this part so it can function, although the groove for the o-ring is tight so a face seal gasket must be used.

Hope this helps someone!
