This is the plastic part of the shower diverter for a Delta faucet. I didnt want to pay $17 for a plastic part so 3D printing to the rescue. Hopefully, it can benefit others. I printed it in PETG horizontally with dense support. Works pretty good with initial tests. Some water still comes out of the tub faucet but works otherwise. I don't know the longevity of this part yet. I will try to update in the future if it holds up.
