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

  • U van probably get some improvements by dialing in the printer settings. Otherwise just change the geometry would probably be more effective for less effort. I would reccomment circular holes with the same area as the existing filter would help reduce the issues ur seeing with overhangs. And maybe turn the cooling fan up a touch to help reduce stringing but it probs wont be too effective considering the material.
