Trinity Knot EDC Spinner Fidget

thingiverse

I've got ADHD, no big deal. Classes have been a real challenge for me lately, so I figured I'd create my own fidget spinner. I've seen these things all over the internet, but I wanted something better. The central hole on this spinner is precisely 22mm in diameter, matching the outer diameter of a 608 bearing. I deliberately left no room for tolerance, planning to sand it down to size later. The three orbital holes are identical to the diameter of a US quarter, which seemed like an unnecessary expense when you could just use quarters instead of bearings. By doing so, I saved $5 on bearings and had $3 left over for quarters. Coincidentally, a standard 608 radial bearing is 7mm thick, and guess what? A US quarter is also 1.75mm thick – that's 4 quarters stacked up at exactly 7mm. Anyway, happy spinning! I'd love to see the creations you all come up with.
