CR1225 container for camera button

This is a small, very compact case for a CR 1225 battery, adapted for a cold shoe slot. I work as a reporter and often use a selfie stick with a Bluetooth remote control for shooting footage. Unfortunately, this remote does not have a battery level indicator, and it has turned off several times in the middle of recording. Since this selfie stick has cold shoe slots for a flash and a separate microphone, which I don't use, I decided to use one of them to store a spare battery for my remote with a camera shutter button. I made this container out of PLA and PETG plastic; both are shown in the last photo attached. The PLA version (green, made with 0,2 hotend) fits tightly into the slot and the battery does not fall out of it. The PETG version (black, made with 0,4 hotend) fits more easily into the slot, but it also stays in place well and does not fall out. However, the battery is not attached to it and should be held in place when you pull out the container so that it does not fall on
