I picked up a "non working" P645 a few weeks ago. 120 insert & 80-160mm lens, for a bargain price. I managed to get it functioning by installing the hand grip from my existing P645. I preceded to open up the hand grip. I found the issue, corrosion on contacts & a loose wire. Probably caused by said corrosion. I bagged it all up & brought it home. I cleaned the contacts & screws & soldered on the broken wire. BAM! Working again. Now to the battery holder. I am going to attempt to 3D print one, or, 3D print an attachment that mounts to the tripod socket, that connects to the remote battery port.

Has anyone here attempted to print a battery holder?

There is definite market for the 645 battery holders. If you successfully 3D print one and test it and it works, please let us know and if you'd be willing to make more and for how much $$?

Will do. I do know there is a market. I am working on out a design now. Mos likely with rechargeable battery cells.

My two cents: When I can escape into the time and world of shooting medium format film, the economy of rechargeable cells is too much of a trade off with the shorter life. I use only lithium cells with my 645 now. With age on my 645, the slightly higher voltage from lithium cells makes it more reliable.

My vision is to incorporate rechargeable lithium cells into the pack. With a charge port and possibly a level indicator. I was actually looking up the cells last night.

EDIT:
My initial design my use currently available rechargeable AA batteries, such as Eneloop. Then go from there to the actual rechargeable, fully encased, battery pack, which is the desired result. I will post here when I get the first unit put together.

Is there a trick to removing the top plate of the grip? I have removed the mounting plate but the top plastic plate seems to stick on the outside edge. Don’t want to risk breaking it.
