You'll need to post the overall volumetric size of the individual parts and a rough diagram of it and it's function so people can judge if they even have the print volume to produce the parts as a whole and if they want to take on the project. To give you an idea, most printers that aren't large format or more costly are going to have a build volume of around 200mm x 200mm x 255mm (7.87" x 7.87" x 10").
Depending on the overall dimensions, 10 inches isn't too big for most printers if you can print that longest dimension in the Z axis. Whether or not that is an option will depend on the kinds of stress the part may be under, since you might want to orient the part in a specific direction so that it can be strongest against whatever those forces are. What material will be best will also depend on the environment (regular exposure to moisture, how much heat, etc.). There's a good chance it'll need to be engineered to be made in pieces and then you have to determine how best to assemble the pieces to make the entire assembly (threadserts, snap together, etc.).
Edit: (I hate the forum feature that stuffs a second post into your previous if you were the last poster.)
Even after the bed changes, the shrink forces are still causing lifting of the first layer. I've been playing with modifiers in Orca to combat it and I'm getting improvements, but it's still a problem on this end. I'm going to try 75% infill in these corners and add a brim there.
