1968 convertible hold downs

I've been trying to locate both drivers side and passenger side conv top hold down. After searching for several years I found a 3D printer that's going to make me a 3D printed set out of SS. Anyone had any luck with that sort of thing?

That’s a great idea. Are those on the windshield or the back holes/latches that hold the back down ? I’ve got the same year and the only latch on the windshield that holds is the center one. The others are still present but they don’t add any staying support for the convertible top. Hasn’t been an issue but I wished they did work.
