The pencil twins

by Thingiverse
Are you looking to make some anaglyph / calligraphic things or maybe just a fun thing to occupy your children?
Don't move, "The pencil twins" is for you!
What is it:
It allows you to gather two pencils in one. You can mix pens, colours or just use the same pens to have a perfect same trace.
It is ergonomic and thought for your fingers, big or small!
It’s smart or at least easy. If your pen is stuck inside you don't have to take a hammer to extract it. Simply spread the sides out and your pen will gently slide out.
"The pencil twins" is designed to accept pens with a diameter of 10 millimeters.
