OASE skimmer - perforated mesh

I was thinking about how to prevent fish from accidentally swimming into the skimmer when the basket is being cleaned. So I created a simple screen that is placed on the skimmer outlet when the basket is not there.

The part is primarily designed for the OASA skimmer with an outer diameter of 165mm - it is made with a relatively small clearance so that the water does not float it. Alternatively, you can gently grind the inner diameter or slightly adjust the scale in the slicer.
