Hmm the idea with the universal tripod mount is pretty neat. But I am not sure about the mounting pin - that one is much harder to make universal.
The grip needs two attachment points so it doesn't rotate. In the last of my pictures you can make out the other end of the pin in the bottom left corner.
I guess I would have to design a lot of individual, selectable pin positions. But that would be possible. I would just need one of every camera body to test it properly
Exclude the mounting pin from your design, and include a very thin square piece of rubber sheet to go in between the grip and the body, with the tripod screw through the center of the rubber to keep it in place. Then, once tightened down the rubber should keep the grip in place without the need for the pin. Similar to how the Black Rapid straps connect to the tripid mount.

Should you make the effort to design one for the K-5 system, consider me a potential customer ;D

this is awesome! I have been using my K-5, wishing for some kind of battery-grip for 3 1/2 years now and your idea could just be that solution. I never wanted to put up that money for a simple grip so a cheap solution like yours would have me as a customer in a heartbeat!

keep up the good work

I hope you used a Ricoh 3-D printer.

Great idea! You could make some for cameras that doesn't have a grip available, like the k50, k30...

Neat!

How does your K-3 handle in portrait position?

Why canikon red and not Pentax green? Or is that Ricoh red?😁All joking aside, nice work. You should take orders and have a batch done for those interested.

Haha I didn't know about Ricoh 3D printers

I don't plan to make a serious business out of it, but I could have some more printed for interested Pentaxians here on the forum.

The catch is - because it is not mass-produced but 3D-printed, it is not really cheap. The cost would be similar to that of those 3rd party battery grips
But then, you could have any color that you want!


@luftfluss
It also improves portrait handling - more hold for the little finger helps here. Plus, if you hold the camera the wrong way round (rotate clockwise), you can hold the camera by the grip with the left hand. I sometimes do that with the small primes

Looks like a great idea!

Consider releasing the CAD files publicly unless you want to make some money

Then people could get them printed at online 3D printing services (ie: Shapeways) and modify the design to fit their camera.
