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.
