Picture frame (A4)

Model consists of 4 bars (two sides, upper one and lower one) and four connection pieces. The longest one is the side bar and can only be printed diagonally on the bed. Lower bar has two integrated latches that hold the picture from the back. Latches also allow (after folding down and removing lower bar) to swap the picture.

The solution assumes the use of 5mm Kappa board (see pictures). I also added protective blank laminated foil in front of the picture. (Grooves in the frame are 6mm wide.)

Use the connection pieces to connect the bars.
