HO scale brick wall

This is a brick panel meant for use in HO scale, that can be printed on a FDM printer. To be clear, this is not to scale. The mortar between the bricks is a 1mm wide, which would be like having 3 inch mortar gaps in an actual brick wall. The goal was to make something that is easy to print, and easy to finish, and still look good at HO scale.

The panel in the photo was printed in black PLA, then finished with acrylic paints. First coat was a light coat of brick orange. Once dry, I laid gray on thick, then wiped it off with paper towel (sometime wetting it). This rubs off the excess 'mortar', and actually rubs off some of the orange, giving it a weathered look.
