Needed a way to take my phone with a old-fashioned costume without it being conspicuous.

The phone clips into the tabs on the back cover. The front cover, back cover, and spine are glued onto some sort of fabric to form the cover. I used leather. Gluing in a liner and headband and footbands were a nice finishing touch but not required.

The pages are printed in white. The end of the lever on the power button is glued to the pages with a very small drop of CA glue. It is designed to flex to allow the power button to be pressed.

The phone is clipped into the tabs on the back cover and then the pages slide on around the tabs. The phone cannot be removed without removing the pages as the case is too rigid.

The case is held shut with two small magnets on the front cover and pages.

This model fits a Motorola Moto G Power 2021 perfectly.
I have included the DesignSpark files so it can be resized and the button moved to fit other phones.

For the back cover, I found it easier to sink it into the bed in the slicer 1mm to remove the border. Then I printed an extra copy of the border separately and glued it on. It doesn't have to look good because it is covered by the cover fabric and printing the border separately prevented a ton of cleanup vs using supports across the entire surface.
