Unfortunately having printed this piece a number of times I have found that the lock box which is meant to link/lock the chain DOES NOT print to scale, rending the piece unusable as far as casting is concerned. The Cuban links print accurately and look really good when connected however the lock does not. Such a shame as I have tried to contact the seller a number of times over the past three months and they have not responded once. This has unfortunately left me out of pocket with a design I cannot use - Don’t waste your money as I have.
