Introducing the latest toolhead for your Makerbot!

The Unicorn extends the capabilities of your Makerbot into the 2D realm. You can make unique stickers, diagrams, UPC or QR codes. Sudoku puzzles, digital photographs, logos, you can even mark up PCBs for etching!

Pick your favorite pens, markers or drawing implements, load your raster or vector art files, and watch your machine draw! It works by holding a pen, marker, swivel blade, or something roughly cylidrical and then uses a hobby servo to lift the implement up and down as your xy stage moves around. It turns out it’s perfect for drawing on sticky notes.

This new toolhead for your MakerBot that can bring a breathe of fresh air into your 3D printer by transforming it into a machine that can make 2D art and more!

Somehow the "required parts" section of this thing seems to be missing.

what's the (electrically) largest size of servos we can use?
I'm interested in designing a printable version.

wait a minute....why does the plotter even need a servo at all?

It's located on the Z-stage.

Is there a centering technique? I am Imagining how the pen attaches and it seems that different size pens/markers will have slightly different centers.

Any chance we can get a part number and supplier for the linear slide?

like in the makerbot store? sold with a servo? hint hint... :-D

It looks like the rail is a cut-down section of:


Not sure which carraige is the one makerbot has picked - I couldn't find the dimensions of the various carraiges, but presumably it's one of these.

Finally! A printer that really works!!

This is amazing! Is a printable version in the works?
