Simple photoframe /stand for 10x15cm photos with side or backlight. Allows you to print and use photostand for standard photos with vertical or horizontal placment. With use of some cheap led strip you can make interesting lighted photo frame. The back plate is only used for placing of led strip - either glue it on sides of back plate or with some more work you can glue it in square pattern inside of the backplate - in this case some cutting and soldering will be needed. The power cable goes in this case thru the square hole in bottom part of backplate. The used Bambulab PLA tough filament is translucent, so it will be nicely backlighted. For my photo it didn't looked well, so I choosed the placing of leds on sides. The backplate is not needed, if you don't plan to use lights.
