About this 3D model
I made this satisfying Zippo replica that features the same hinge principles as the original. The model can be printed withing an hour using 0,2 layerheights. For the hinge axles I used 0,85mm jewelery wire. the hole in the 3D model is 1,125mm diameter. I was quite surprised of how wel the sound compared to the original. You can put some weight in the bottom using superglue, I used old small bolts and nuts I had laying around.
