Geneva brand steel kitchen cabinets were popular in the 50's. They featured a low profile cabinet handle that required a recess behind the handle. This was made of plastic. Today, these cabinets are popular for retro style kitchens. The durable steel cabinets are being powder coated with all kinds of colors. The plastic handle backing plates however are all but non existent. They only came in white and there are no sources for replacement.
I recommend ABS for this application. I print them with support and with 100% infill. I plan to vapor polish them when they are done.
