The file 'Wanhao Duplicator I3 Filament Holder 3D Printer Model' is (stl) file type, size is 23.7KB.
These brackets hold three roles of filament at one time, and are designed specifically to fit on the Wanhao Duplicator i3. They clip on the top, from the back, and come down over the top two screw holes on each side. You have to take the screws out, put these on, and then replace the screws. Be careful not to over-tighten. And when you're clipping them on, they will need just a little elbow grease to snap into place. It's a tight fit, at least for my printer.
I used a 1 inch diameter threaded pipe that is 12 inches long with two end caps as the bar that goes between the brackets, and it works great.
Now I have three different filaments on my printer ready to go without changing them.
