Filament Dual Wheel Pully

thingiverse

I have a Tevo Tornado, but as you can see in one of the pictures, some of my spools sit on the far side of the printer from the extruder. So I modeled these double pulleys that let me run the filament from the one side down to the extruder without risk of running into the head. The pully bases are designed to perfectly slide onto the frame rail. You will need to print two wheels, two pins, and two pin caps per pully base. Put the wheel in place, slide the pin through it and put the pin cap on the end. You'll need a bit of super glue (krazy glue) to glue the pin cap on to the end of the pin. Also, I recommend the long pin for the wheel on the end, and I would glue the cap and pin base to the outside edge of the pully base. That makes it so the wheels don't rub the sides as much, making them spin easier.
