3D Pens

As a little kid, I thought it would be so cool to be able to draw in the air. I imagined a crayon that just left marks on air, that you could scribble with to make a costume or something.

The real deal has come. It doesn't exactly write on air, but it basically does. Here's a diagram of the controls from the newest 3Doodler Pen model:

And yes, there are multiple models of the 3D Pen.

And yes, there are tons of super amazing videos of pens in action.

For example, this person made a pair of scissors that really cuts using a 3D pen.

There are also tons of tutorials online if you have a 3D pen.

If you don't, you can get one here for $99 (shipping not included).

Here's a video of that pen at work:

If you have $99 to spend on a pen, then I highly recommend you get this pen. You can also purchase different tips (nozzles) and holders for the pen at the same link above.

Anyway, have a good day, thingologists! See you tomorrow!
