INTEX BESTWAY Pool Skimmer adapter Ø40(42)/Ø25 mm

My remix of the reduction of the diameter of 40(42)mm to a cone of the smallest diameter of 25mm.
I designed the model based on the original parts from the pool that I wanted to "assemble". But the original idea of @rebeltaz I kept.

Making PETG TRANSPARENT

nozzle 0.4

layer 0.2

infill 100%,concentric

Print cooling off

For printing, rotate the model with a larger diameter toward the bed.

And as always with functional rather than decorative prints I recommend calibrating the prints on the printer using the advice of @SteveHanov, I recommend the link:
