2. Prepare materials first, and pay special attention to the selection of main materials. What I choose here is a flat tempered film, which is relatively large and easy to cut.
3. Draw the size first, which is 1cm. 6cm at the bottom. Height 9.5cm, draw a cross first, so that you can confirm the middle position.
4. Put the prepared main materials on the paper, and then carve traces according to the lines, preferably with a ruler, so it is not easy to carve them out.
5. Carve the material into a painting shape along the carved marks. Be careful not to carve it. Then stick it with your feet.
6. Now the 3D projector is fixed with glue. The reason why glue is used is that there will always be gaps when the tape is bonded, which will cover a part. It is best to fill the gap with special glue for shoes. The 3d projector has been completed.
