Thanks, Michael. This would be very useful for astro shoots where you do not want to tear anything down to add a battery.

Exactly! Now if someone could design one that allows several batteries in parallel

I would have appreciated if a detail showing the how the contacts on the adapter itself were crafted as well as the pin mappings were included.

This would be more useful for me. I can see having a green one for charged batteries and a red one for depleted ones being handy when travelling.

I don't get it either. A grip adds balance and is marvelous for portrait shots and large lenses. Shoehorning a battery on top seemingly would throw the weight out of balance....

During my astrophotography sessions, I often must remove the grip if the subject is within 40 degrees of the zenith due to the ballhead height. Thus, I lose the use of one battery. This battery holder fits on top of the hotshoe and does not get in the way of aiming the camera. So it is a win for me. Steve - I will post a photo of the finished product after I pick it up tomorrow. As it happens, there is a 3D printer in town here and he knocked it off in less than an hour.

additional usage is that you can achieve a zero down time of the camera. even when using a battery grip you can mess it up and wait to long leading to two batteries with no power... as you have no access to the battery in the camera while the grip is attached...

For when you need to shoot for an extended duration without being able to move or even touch the camera.

Ideally Pentax would allow people to use the camera and charge the internal battery with a USB power source. They are everywhere. New cars come with a USB charging port, and you could easily buy one. Portable USB batteries are everywhere. etc.

That is awesome! My D-Li90's last forever, but my Sigma SD1 Merrill takes D-Li50's and they are basically like film rolls... 36 shots on a pack. I'm gonna download the STL and mod up something to carry my pile of 50's.
