A haptic "slider" fidget using embedded magnets, PTFE (teflon) rails for low friction sliding, and stainless steel bearing balls to limit the motion and make it easier to fidget with due to the double-decker design that allows the filling to slide as well as the cookies. This fidget has 27 magnets, but it's not hard to slide because the magnets are embedded, and therefore not touching each other. If the bearings are removed, it will still work fine, but you'll have more range of motion. The PTFE rails can also be removed, and they pop right back in by hand. Without the rails, the pieces can slide in any direction, if you feel too limited by the rails and bearings. The Oreo Double Stuff Slider is NOT scented.
Note that this is my design and not available for home printing. However, it uses the free Oreo Cookie model which can be downloaded here for your own uses. https://www.thingiverse.com/thing:3391808
If you'd like to buy an Oreo Double Stuff Slider from me, they are $40 each, including shipping within the USA, but can be shipped internationally at additional cost.
