automatic door closing mechanism

Hello

I have several pets that freely enter and exit my room As I dislike leaving my door ajar, I needed a solution, hence the idea of a door closer Since I am not particularly adept at technology, I opted for a simple rope and pulley system As the images above illustrate, the implementation proved successful However, you will require additional materials beyond the printed parts You will need a cord, a weight (in my case, a small, flat container filled with water), and finally, double-sided tape or screws, depending on your preference

Instructions:

For assembly, begin with the weight Securely knot the cord to the weight and place it on the floor behind the door Next, thread the cord through the first pulley, then to the second The attachment of these is shown in the images Now you should be at the door holder Pull the cord taut, ensuring it does not sag, but also taking care not to overtighten it, so as not to strain the components when the door is closed Now, simply secure the cord to the door holder, and you are done

I hope it works for you

Enjoy!!!!
