Bates Motel sign from Psycho 1:87 HO scale

I converted it to obj format, made it manifold, sized it up, added the vacancy boards, and trimmed the bottom to fit on a small resin printer. The sign is sized about right for the vintage Polar Lights model kit of the Bates mansion, which is what I'm using it for, but it could be sized up or down (or printed hollow to allow for a lighting kit?) to match whatever you're going for. I printed mine hollow, flat on the print bed, no raft but with light supports.
In the original Psycho movies, the sign has no base, just two poles coming out of the ground. In the TV series, it has the planter base. I'm including both versions. If printing the one from the original movie, you'll need to add a raft and cut or sand it off after printing.
Happy Halloween!
