Hi, I have a similar issue with my camera.
My holder is cracked but not broken, so the camera is fully usable for now.
Last week I asked a friend of mine to 3D print a new battery holder, not the usual 6xAA, but a converted version that will require 2x9V.
After a bit of sanding the piece fits well (there's a gap on the side but we will probaby print it again). In the next couple of days he will complete the wiring, I believe in the converted model is quite straight forward.
This is the link to the
3D part
There's also a traditional 6 battery version from the same user
I will keep you posted if you are intrested
