This is a keychain made by an impeller and a supporting platform. The rotation of the impeller is smooth and regular indepentently of the accuracy of the printer you are using since the tolerances are choosen to be pretty high.
If you are an engineer or an enthusiast about mechanics or fluidodynamics and you like to fidget with stuff this is the keychain for you!
Original impeller design: https://www.thingiverse.com/thing:2426666
Print the impeller with 0.1mm layer heigth and 25% - 50% infill to keep the weigth low.
Print the support with 0.2mm layer heigth or more so that the chance of it snapping is lower.
Scale it down as much as you want. 65% (**both**) for 4cm diameter
