4 inch Exhaust Duct Tee with Waste Gates

I had an existing vent system for my HeyGears SLA printer, and wanted to adapt it to vent my new BambuLab H2S as well.

To do that, I needed a Tee adapter, with 2 wastegates so I can choose which printer (or both) to vent at the same time. 
Came up with this simplistic solution that works great for me.

I'm a beginner with Fusion 360, and this model can probably be significantly improved in many ways, so feel free to remix and share.

Hope you find it useful!
