My wife has an Xbox Series S and sometimes plays remotely so carries an extra battery pack for the controller. I created this case to protect the battery pack from damage or anything shorting out the terminals (such as keys in her handbag :P ). I included a picture of the battery pack for reference.I thought I would upload it here in case anyone else had the need for one of them.
it is basic but does the job and the battery does not rattle about inside.
As mentioned in my profile I am new to 3D and this is my first self designed print so all constructive criticism accepted (good or bad)

Originally designed and printed for the Ender but adapted it for PS1
