Four gear sphere fidget

This is sphere fidget made up of four gears that rotate simultaneously by moving one of the four knobs on the outside of the sphere. Please note: printing this fidget requires that slicer add supports as it is done in the provided .3mf, so for proper supports removal after 3D printing, it is strongly recommended that you let the print cool completely on the 3d printer-bed (which can also be removed from the printer to be quicker). In this way, once the print has cooled, the supports will come off cleanly with a sharp tap.After the supports have been removed, two knobs must be gently turned to free the gears and allow the fidget to function properly.At first, the gears will not feel completely free, but after a few minutes, they will turn frictionlessly and you cannot stop to use it.
