Art Ahmshord 3d Pen Thing

I didn't really have the right filaments to get the correct color or any grey filaments so i couldn't really do the inside walls, also ran out of brown so the mid section is a bit bare, sorry about that. this was mostly meant for just practice work but i thought i would show it so tell me what you think :)

That's pretty cool
Where do you get 3D pens

 

http://www.scribbler3dpen.com/ there are like 5 other brands of 3d pens but this is the one I bought, they are fairly expensive though

 

Fucking beautiful

 

This is amazing :o

 

How do you even draw in 3D? Damn, that's cool! ;D
