My buddy has a cold plunge and this filter started cracking. After looking at it you can tell it's definitely 3d printed (and well)

On the left you can see my first attempt. I just cut rectangular holes in CAD and it's pretty close but not pretty. Printed in PETG on a K1 Max

Is there a way to do this in the slicer instead? I played around with 0 walls and different infill types but that didn't work out

~~Tangent: That sounds like a bad idea for food safety. And I'm referring to both the original and the recreation. If it were for myself, I would buy something made of metal.~~ edit: Thought it was a coffee thing, disregard.

On topic: Could you clean up the holes with a hot needle and some patience? PETG tends to be very stringy, which is probably the reason the holes are not well defined. Maybe try tuning your printer to minimise stringing?
