Polaroid-Inspired Split-Flap Picture Frame!

I designed this as a Valentine's Day gift to my wife for displaying family pictures on her desk (the stock photos shown are not family lol).

This photo frame holds 8 wallet-sized (3" x 5") photos. Rotating the crank changes the picture shown with a satisfying clack.

Assembly instructions:

1. Use one of the flaps and a sharp blade to cut your photos to the right size.
   • Tip: mark the tops of each photo beforehand, and use the same side of the flap for the bottom of each photo. I use the side with the thicker bottom, as this is the bottom of the Instamatic prints

   • 

2. Slide the photo pairs into the flaps.
3. Arrange the flaps into one of the wheels

   • 

4. Line the other wheel up carefully so that the squares line up. Slide the top wheel on, sandwiching the flaps between the wheels.
   • This may require some careful positioning and patience.

   • 

5. Slide the assembly of flaps and wheels into the housing so that only one flap sits in front of the bottom stopper.

   • 

6. Feed the axle/shaft through the right side.
7. Attach the crank handle
8. (OPTIONAL): Pop on the TPU feet

If the flaps become stuck:
Turn the whole assembly upside-down, spin the handle opposite the normal direction for half a turn, then while turning the handle in the normal direction, flip the frame back right-side up.
