I just couldn't find an existing model that had both sd and usb stick storage.
I recently purchased a new laptop and the carry bag is slim with small front pockets, no where to store some vital sd cards and usb sticks without them just floating around in the bag.
After searching around I ended up integrating the best bits from lots of different models floating around on the internet from images and created my own from scratch.
There are also 4x holes for gluing in some magnets (4mm diameter x 2mm high) to keep it closed.
Add the stl to prusa slicer and separate into objects, then you can lay each of the sides on their backs to print.
