Hi, I would like to offer you a set of barricades that I used in my projects. The scale is for 28 mm high figures, such as Warhammer, Necromunda, etc. No support is required for printing, the barricades are composed of parts that you can print directly on the substrate. The parts contain small holes for magnets. I used the usual printer settings for detailed printing. I use an Ender 3 printer.
