This design allows you to mount a rifle stand onto your atv luggage rack. This design was based around the rack on my 1994 Polaris Xpress 400 but may work on other models. As of right now I have not designed a strap for it and am debating on whether or not it's better to just use an elastic band. I printed mine out of TPU and am satisfied in how well it grips without marring, It conforms to the shape of the stock pretty well. I have only printed the models that have the stand on the edge of the base plate, oriented so that the stand is flat on the bed. It does not require supports.
