This is a fake towbar (Europe size). I use it as an insert in my caravan, so other people can't hook it up. I use a lock and chain on the caravan stabilizer so the insert can't be removed. There are a lot better caravan locks on the market, but they are heavy. This is a lot easier to break, but it's a good weight compromise. I used PLA, but for better security ABS will probably be better.
