Đế giữ pin D-Li90 cho máy ảnh Pentax

When packing my camera bag I never had a good way to store my batteries, so I created this holder.
Pentax labels these batteries D-LI90, I have seen similar ones designated D-LI90(E) and D-LI90P.

Bend back latch, insert/remove battery, done.

I noted that the dimension of aftermarket batteries are slightly smaller than OE ones: The holders do keep all types I have encountered so far reliably. I do store full batteries with terminal up, empty ones I do insert with the terminals down. Empty/Full labels are on the holder accordingly.

Print text "D-LI90" facing up. I do recommend PETG as the latch needs some flexibility.
I got away using no supports, the imperfections in the battery compartment did not prevent the battery from fitting. Alternatively use supports as required.
