Carousel Hub

I strongly advise against utilizing 3D printed replicas of this product in 4-Mation, unless you're employing an exceptionally robust filament. Primarily designed for individuals to prototype a Lego carousel before acquiring a 4-Mation kit featuring a precision-machined solid perspex hub, it can be a viable option - as long as you're using a high-quality polycarbonate filament like PolyMax PC and are able to print it without warping.
