Hi, yesterday, I printed a prototype of the battery. Currently it is the hollowed-out version (look into uploaded files) cut into two pieces. Therefore it still lacks features for screwing together the battery case and for mounting the PCB with contacts. However, it seems that it can be printed just fine, it fits properly into the camera and holes for the contacts are on the right positions. Since this is a first time for me when it comes to designing a 3D model, I would say that it is going better than expected. I know that it could look better if I removed the ridges on the top of the battery, because these cause the print to become spaghetti-like at the edges, but since it is possible that other cameras which use this battery may have "anti-ridges" which serve to reject wrong battery type with similar case, I am not going to remove them. Next time, I hope I will have all the mounting features done and case printed so that I can go on designing the tiny PCB with contacts.
I have measured the battery and drawn a model of it. It can be downloaded from this project page in case anyone wants to use it for their own project. Consider the model to be under CC-BY-SA 3.0 license (may be changed if Nikon gets upset), however if you would feel any urge for even more copyleft license, I can release it under WTFPL.
Right now, it is only the outer outline of the battery. No pockets inside, no features for fixing the PCB inside. Will come later, stay tuned!
