I printed this with a raft, since I haven't been successful at printing flat things with holes on a Makerbot without, but I'm also pretty lazy about cleaning up the non-visible side.

I have a house from the 1900's where the doors have changed position over time, and while filing out the strike plates isn't an uncommon fix, I found that in some cases the mismatch between the latch and strike plate was more extreme. This is a copy of a standard strike plate so that I could move the holes around to prototype it, with my thought being that I could have it cut into sheet brass once I'm sure the shape is right.

However, at standard settings, they're surprisingly durable, and in black, tend to be not very visible, so I'm not in a rush to get brass ones cut ... now that the doors latch again.
