looks like you ae doing a nice job, the .300thickness should be plenty sturdy. If you use PETG filament it will be strong. I have built some structures that had to be done in sections and found a couple of things that worked, one was using a "V" design to align the walls with each other. (if you go into the "3D Printing Repository" on this forum it has a lot of design ideas and even stl files you can download) The other thing I did for strength and perfect alignment was to incorporate holes in each section to accept a .125 dia styrene rod or tube to go in aprox. .300" deep in each. I used a good liquid plastic cement after wiping the surfaces with alcohol. I've also used 15 minute epoxy for sections where I needed a lot of strength. If you get the alignment right the seams are pretty easy to hide. Of course all the pins and holes would have to be designed into the walls before printing.
Can't help you on painting those bricks.
Thanks for the tips. I saw your design with the dowel joints. I was going to use that for the joining the building corners. Another question that comes to mind for long multi section walls. What kind of finishing do you do, if any, to the joints. ie. sanding or buffing of some type.
