Seat belt clip
thingiverse
Every time I tried to fasten my seat belt, the irritating clasp was stubbornly slid down between the door and seat, making it inaccessible. A search on Thingiverse yielded a design that required a tack, but I couldn't find one where I was. After some delay, I designed my own solution for a 50mm wide belt, which worked great in my Mercury Villager.
