About this 3D model

Had a Pimoroni Fan Shim shipped to me with the fan broken away from it's duct. Whilst waiting for a replacement, I decided to move ahead with a project, and decided designing a replacement fan duct was in order. The fan's central motor hub was intact, so I simply created a duct with mounting point for the hub to press into, along with stronger tabs holding it in place. Fan works as intended with no spin slowdown. The fan's height is only ~.5mm higher than the original.
