I received these prints the other day from Shapeways. It took some trial and error to get the sizes just right due to the shrinkage and other factors in the manufacturing process. I really appreciate Shapeways customer service working with me on getting these printed as there are a few critical areas that are below the general minimum wall thickness and detail level for stainless. I love the way these turned out. Especially in the bronze finish.
I've had a few other designs made through the last few years as well:
Note: While I did research and haven't found any law in the US restricting the buying/manufacturing of handcuffs/keys, (only laws against where some can be taken and how they are carried) to avoid any potential concern about potential misuse I am currently only selling these to verified Law Enforcement / Security personnel. I am also only offering them in the stainless steel -based materials and not any of the materials that could be used to circumvent a metal detector.
