I had my Octo Pulse 2 pumps out of the tank the other day for cleaning and I was thinking I should make some Anemone guards! Well here it is hot off the printer. This is a direct replacement for the cover that comes with it. This is in black ABS. Probably should be black PETG which is less likely to crack with all the thin walls in the print. Haven't tested it for flow ...don't have an Anemone, but hey you never know! It does connect nicely in place of the stock cover. Holes are 5mm x 6mm high Does that seem like a good size to protect an Anemone from getting sucked in?
