Tri-Arm Fidget Spinner

Take fidgeting to a whole new level with the Tri-Arm Fidget Spinner featuring Advanced Grip Technology! Our Advanced Grip Technology makes fidgeting effortless with its rounded design, unlike many other spinners with sharp edges. Furthermore, the spiral shape of each arm forms a comfortable crevice where your knuckle can fit, allowing you to fidget with one hand while achieving superior spin speed single-handedly. Instead of using standard 608 bearings for the outside, we used high-performance 625s to create arms that feel natural and thin. Amazingly, these small 625 bearings still provide the necessary outer weight to spin extremely well! We've also developed a unique plate sandwiching system that allows easy and repetitive removal of the bearings. This innovative system involves three M3x8 bolts, three M3 lock nuts, and three precision 3D printed spacers. The 3D printed spacers ensure that the bolt head doesn't sink too far into the hole, exposing its sharp threads on the other side. To simplify this process, we've created a comprehensive YouTube tutorial video to guide you through it!
