split support ring to allow multi-colored print and assembly

the OP was nice enough to break this fidget gear assembly into different components, however the model was still a print in place and as such could not be disassembled or assembled. The herringbone gearing prevents the gears from being slid in or out of the housing. To fix this dilemma, I split the housing in half down the line of the herringbone spine and added rectangular pins that can be glued to re-form the housing solid. In this way you can assemble the planetary gear without any issue. I purposely did not make the pins symmetrical so there is no ambiguity as to how to rotate the two halves and I also put two bumps that align on the outside to indicate which in inner sides of the two assemblies.
