HO/OO Rail Painting Mask

thingiverse

This is a straightforward paint mask that clips onto your HO or OO model track, allowing you to paint the sides of your rails without getting paint on the sleepers or ballast. It works equally well with an airbrush or a small paint brush. The clever design includes various bevels that give you a clear view inside to paint the rail sides with minimal effort. As you paint, the mask tool glides along the track - notice the two block shapes at either end, which slot between the rails and serve as guides. To achieve even coverage, paint one rail for a few feet, then work back to cover the other rail on subsequent passes. Repeat this process down the line. To further minimize over spray, I've added V3 files with a longer mask shape that includes slots on either side for a piece of card to act as a backstop. I've tested it with a business card and it works well. If you have any additional ideas or suggestions, feel free to comment below. Otherwise, let me know how this paint mask works out for you!
