The file 'Hammerclasp 3D Printer Model' is (stl) file type, size is 276.6KB.
It's a simple bracelet-style clasp: tie a 3mm-ish cord in the tail, tie a loop on the other end. Loop goes over the hammers.
I saw something similar on a certain e-tailer website for $40 in bronze, I figure I can do better.
These are printed in metal (solid bronze), then post-processing heavily to apply filets and smoothing.
