About this 3D model
Make anything in to a magnet or a hanger by adding positive and negative parts. These are examples of fridge magnets and hangers all originating from the same model. All I did was add a negative cylinder which is similar dimensions to the magnets I have. For the magnets I have, which are 6x3 mm I added a negative cylinder which is 6.3x3 this make sure that the magnet will fit with ease. If you have magnets of a different size, all you need to do is adjust the negative cylinder to the dimensions you have. To make anything in to a hanger, all you need to do is add a positive cylinder and then a slightly smaller negative cylinder. Have fun printing these models and experimenting with adding shapes in Bambu Studio.
