Really liked RodLaird's design though the batteries were a little hard to extract without the thumb tabs. Also, given I always have one battery in the camera, I didn't need a four battery holder.
Great file, thank you very much for that. ☺️
Now my batteries are no longer lying around openly and i have order!
I also added a print profile that was perfect for printing.
I also made a label in this STL with Sony A 7 so that I can immediately see which batteries are in there.
