Nắp chặn cho ống nước Intex Curved Jet

I've been using the Intex Curved Jet Model from Thingiverse with great success, except when it came time to swap a filter. A plug for the filter outlet came with the pool, but it's a different size than the curved jet. This model will not create a water-tight seal, but it will prevent an uncontrolled backwash into the filter canister.
