This is another entry for devonjones' amazing OpenForge series. This time, a door. It's a remix of his arched doorway combined with the rougher stone terrain.

There exists a very similar piece on Thingiverse already ("Stone Dungeon Floor with Arched Doorway (OpenForge compatible)"), but I had some problems printing it, and I think the area immediate underneath the door in this model is a little better looking than in that one.

Update: I realized the reason that I was having trouble printing the other one—there is an error is part of the arch model which causes gaps. This model has that gap fixed and should print correctly.
