Simple Hidden Picture Frame Mount

Our toilet calender (very Dutch thing) was hanging from a hook and fell down breaking the original frame. We bought a simple new frame and wanted a mount that allows for easy replacing of the calender months. This is a simple quick mount I designed in Fusion that allows for easy mounting and unmounting of the frame so we could change the calender out every month. It's held by some double sided tape that are 20x35mm. Holds well, and easy to use.   The mount is only 7mm deep when both parts are connected. If you have a frame where the backplate lays deeper than 7mm from the frame this mount won't work for you!
