I created the model to have my memories all the time and all I need when I'm gone. is quite resistant and the cards and everything inside is safe. This tool can hold: 4 aaa battery 2 Usb stick 1 SD card I printed the model with pet-g but can be with abs or pla. Everything worked well all the components went into their place. I have attached some pictures with the printed model. I hope you like your little box.
