Cover The Interior of the Box With Black Paper

With a knife or scissors, cut out the box’s lid and one narrow side of the box.

Light reflection from the box wall leads to image noise, projecting low-quality images. Therefore, cover the inside of the box with dark or black matte paper.

Make sure every corner of the box is covered with black paper and apply glue for it to stick together well.

If you do not have the dark matte paper, paint the box black, and let it dry.

Install Magnifying Lens into the DIY Projector

Remove the handle and trace its outline using a pencil on the center of the narrow side that was cut out.

To make the magnifying glass fit into the opening, cut out the outline with a precision knife.

Designing the Manual, Adjustable Focus For the Phone Projector

Adjustable focus means that the lens can be moved according to the phone to improve the focus.

Create a second box to fit it into the outer box. Put four sheets of black paper folds and place them at the box’s edges.

Using precise measurements, make some shallow cuts at one edge and fold the flaps. For a more solid and rigid structure, attach the adjacent sides of the flaps using glue.
