Cut out the box from center to make it a two pieces so one pieces can slide into other pieces to adjust the focal lense and make it focus on the projection

after cutting the box staple the pieces to connect them so it doesn't go out of shape

bend the one pieces so it can slide in other easily

Place the magnifying glass over the box and mark out the diameter and cut out that part

place the hot glue on edges and put the magnifying glass over it

Place the brightness to full and off the auto rotation make the video on horizontla and place the phone upside down because the magnifying glass will project the projection upside down

Put masking tape on smartphone edges and secure it on the inside of the cardboard pieces which will slide into

adjust the distance by making it near to the magnifying glass and placing the projector near or far from the wall so it can project with focus.
