Pool filter cleaner type 6

I made this model to clean my hot tub filter from the inside, which works better and faster for me than the other tools just spraying from the outside. It still works well as a sprayer to also clean the exterior of leftover debris. It threads on ¾ hose ends and has room for the rubber washers. I put mine on the melnor hose valve bought on amazon which comes with the washers. Printed out of ABS with uploaded settings to prevent the tool from having unintended leaks and it worked well.
