[GreenKeys] UGC-136 ribbon replacement

[Nick England]

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.

Not sure what we’ll get out of it other than a Bravo Zulu. Maybe a source
for ribbons for the future. I’m going to ask for a photo of the UGC-136 in
use aboard a sub, but probably they are a little funny about photos there….

Cheers,
