The 3D Printing Subreddit has moved to forums.rhombik.com/c/3d_printing . But I can't seem to find it in kbin's search. There was a previous thread asking a similar question about another migrated sub, but based on the solution there, my best guess was that I should go directly to https://kbin.social/m/3d_printing@forum.rhombik.com to subscribe. But that gives me a 404. I've tried the variants with the D and/or the P capitalized, since I gather kbin is picky about that, but no luck. I've also tried it with and without an exclamation point, though I'm pretty sure in this context I'm not supposed to use that.

Anyone know how to do this? Is there any way to make it work?
