Yes, this week I’ve been corresponding with a Navy contractor (SRC) tasked with coming up with a solution for the ones still in use aboard missile subs. He’s pretty delighted that we’ve already done all the work! I’ve given them the 3D files and the ribbon manufacturer contact and he’s already ordered some. I sent him one of our 3D printed versions to test.

Thanks again for more great info Nick,

I remember you said the Navy had reached out to you looking for ribbons? Are they still utilizing these machines and did they ever request any of these new designed ones?

I think this will work for replacing the ribbon in an original UGC-136 cartridge. Either a new ribbon or remove, re-ink and replace an old one.

The 3D-printed cartridges don’t need this mod, because we changed the design from the original.
