A 3d Pen has been made
So I was browsing around and decided to write random stuff on google, at some point it was "Rainbow Dinossaur" but what I found interesting was 3D pen when I wrote it!
It's name is 3Doodler and it's a pen that can draw in the air, it works with heating and cooling plastic to make whatever you want!
