A real big 3D printer can never be entered in you pocket. If you can use a pen as 3D printer? Can you use? Answer will be yes, because now we have 3D pens. Let's make a 3D pen.
Note: the main 1st picture's 3D pen is not real, a miniature 3D pen.

You will need heating chamber and filament. You will also need a body to fit them.
Collect these things-
Option 1:
1. Aluminium can
2. ABS filament
3. Cardboard, many and many
4. Hot glue gun
Option 2:
1. Hot glue gun
2. ABS filament
Option 3:
1. Hot glue gun
2. Glue stick
3. Rubber band(optional)
Option 1

Follow my video to deign. If you can take the filament through the nozzle once, it may go until the nozzle becomes cold.
Note 1: Keep pressure on the filament
Note 2: Heat by fire candle
Option 2

Though, I may not to tell anything, I have given just a description.
Take the hot glue gun and insert the filament instead of glue stick. You must need a mini glue gun for this. Or, it will not fit in your pocket!!
Option 3

Do you know that hot glue gun is a 3D pen itself. Just print with glue(must be a mini hot glue gun). You can add a rubber band like the picture.
