I created a pre-filter that can be made with mesh screen from screen doors or you can print the mesh yourself (see one of the pictures in attachment). There is room for 3 meshes on top of each other so you can collect even smaller debries.

Intex pool adapter based on this design: https://www.printables.com/model/34555-intex-pool-adapter-for-125-hose-intake

=> 2 designs for this part, low profile or regular which allows you to add a chloor tab into this piece.

There is also a plug design so you don't have to unscrew this piece every time you want to clean your pump filter.

Currently you need flex filament if you want to use this design as I used 2 grommets to have a really tight fit.

If you work with Fusion 360, this is the file link: Model

TIP: when fitting the tube onto the adapter or the filter, put the tube on under slight angle to make it easier to slide onto the snaplike fitting.
