Filament maker machine

cults3d

I've designed a filament machine that makes it possible to recycle old PET bottles into filament that you can use for your 3d printer. This is a winding system that works with an arduino uno and a nema 17 stepper motor. The stepper motor is controlled by an L298N driver. This is my 2nd design after the conclusion that with the previous version the stepper motor had to make too much effort to rotate. This has been fixed with the placement of multiple gears. Everything can be printed, but the side plates are better cut/lasered from wood. This benefits the price. The complete machine is controlled with 6 push buttons. They are used to regulate temperature, speed and start and stop the engine. The program code is implemented in the file list
