This is great work. Took me a bit to get the key measuring part down, really is unrelated to the fine work done here. Once I figured out the codes, the key works great. One note, for a standard Kwikset type like and similarly keyed generics, the key fits fine. For the Kwikset smart key lock, although the metal keys fit fine, the 3d print is too thick. I would love to see a slightly thinner key that would fit in these locks but I'm not sure if the printers or the material can do this. Thank you for this.
