I love Trevor Inman's original but I broke 3 of them because I guess I am an ape. So, I thought I'd add a little extra strength. Took about 5 minutes in TinkerCAD but if there are any other gorillas breaking these things, maybe they might get use of the modifications, too.
I use a Flashforge Creator Pro but I imagine the usefulness of this grill isn't specific to that printer.
Print peg-side-up, no support, no raft, I use 100% fill because they're so small and most of it is very thin. Quick build, regardless.
Despite the added strength, the grill is a little delicate so be sure it is adequately cooled before removing from the bed and remove with care.
