Quick plotter mod for Wanhao i3 and clones

myminifactory

This straightforward modification transforms a 3D printer into a pen plotter with minimal complexity and speed in mind. I aimed to keep things simple and efficient when designing this conversion. Instead of replacing the entire extruder assembly, it simply replaces the part cooling fan, making removal quick and easy. However, taking a straightforward approach has its downsides. First, the pen is offset from the extruder, which must be considered when setting up an image for printing. Secondly, good bed leveling is essential since this setup is not spring-loaded; the pen requires a level bed to function properly. Two files are available for download: one is designed specifically for Wanhao V2 printers, while the other is intended for V2.1 models. I based my design on information provided by a friend who owns these printers, so it's possible that the second file may not fit perfectly.
