A simple and easy to print slide in case for your instax mini pictures. I really like to use them as fridge magnets. This way the magnets will never damage your pictures.

It has a built in support but as a separate object if you would like to use your own settings.
The designed support should snap free instantly and without a mark.

Use some glue to attach 4 magnets into the indentations on the back. I used four 5x1 mm neodymium magnet and it attaches to the metal very nicely.
