Introduction: Null

We all know these old spiral plunger spinning top toys? Or these spiral ratchet screwdrivers? So here is fidget spinner design, taking advantage of this simple mechanism. The first key element is of course the spiral screw which allows to convert your pushing action into a rotation. The second key element is a simplified anti-reverse clutch bearing somewhat similar to those found on fishing reel for example. Extra parts needed: - 4mm diameter bearing balls - ball bearing (skateboard type, id=8mm od=22mm width=7mm) - Spring (something like od=10mm length=20mm) https://youtu.be/9TeEaja3DHQ
