Explanation:

These are replacement parts for Hayward Vacuums with "Patented V-Flex™ variable vane turbine technology," such as the AquaNaut 400 or the The PoolCleaner 4.

These pool vacuum work by sucking water from the bottom (from the pool) up through a rotating "turbine" with loose flaps. The rotation of inner gear with the flaps attached to it is what generates the rotation of the wheels. However, both the housing for the flaps and the flaps themselves wear down at the point of rotation, widening the gap that the flaps slide into until they just fall out completely. 

I modeled a replacement flap that would have slightly oversized ends so that they would be retained even in a worn down housing. This avoids needing to replace the central housing / inner gear since even purchasing new flaps would not work or would quickly fail due to the widened and worn down gap. 

Printing Instructions:

6 are required to fully replace all of the flaps. I first printed mine out of PLA and they started breaking after around two weeks, but if they ever need to be replaced it is a relatively short and small print. I recently reprinted them with PETG because the increased flexibility should reduce the likelihood of the end shearing off as it did, and now they last about a month. Ensure to print vertically, as printing horizontally creates unnecessary supports, and also greatly decreases the strength of the flaps as they will shear along their length.
