cooling fan replacement for intex sand filter pump motor 15220

I had an issue with my intex sand filter pump model 15220 - pump was switching off for abnormal heat after few minutes of running.  After disassembly I found that there is cooling fan attached to pump shaft but all the fan blades were gone. This model is replacement of this fan. inner diameter is 8mm (actually 8,1mm in the model to allow assembly without excessive force.

Prototype on pictures is from PETG as I do not have better filament for now. Waiting for nylon.

Lets see how long it can survive :)

both STL and fusion models are available to allow modifications.
