This is an innovative and interesting handheld 3D printer

As shown in the images, ultra compact 3D printer pen is shaped as an easy-to-hold pen
Unlike a normal 3D printer pen, 3D printing pen cannot load any 3D file so your creativity 
is up to your hand
Drawing various 3D models should be an awesome idea if you like drawing
