Wireless printing add-on

This is my wireless printing add-on for my awesome Ultimaker. With it I can print wireless via bluetooth. The range is about 5 to 7 meters, but if the distance gets longer, the signal gets crapy'er and the speed of printing suffers.

This add-on can be used with any 3D printer, if the printer uses serial communication. The module I used is this one: http://www.mdfly.com/index.php?main_page=product_info&products_id=63

If you do not want to have to make the PCB you can buy the break-out board as well:

Here's a movie the thing:

I also made a version which includes a LCD screen, that version is more dedicated for the Ultimaker electronics V1. For more info check out my blog at: http://jjshortcut.wordpress.com/2011/02/19/wireless-serial-bluetooth-module/
