Pool Eyeball (Nozzle) Removal Tool

This tool fits into the slots inside a 1-1/2" MIP thread pool "eyeball" (aka nozzle) so you can unscrew or screw it in. Yes, it fits a Hayward SP1419D!

Note: Make sure to print this in a filament that's reasonably strong and rigid. Those old eyeballs can get calcified and be real tough to remove! I printed the (black) example in AmazonBasics Premium black PLA and it seemed strong enough.

Tip: If you can't unscrew the old eyeball with this tool (it just starts to bend) then you'll need to break out some self-adjusting pliers (e.g. Robo Grip or similar) and really go to town on the old eyeball center part. I had to break off a bit (notch) of the threads on mine and then whack it with some scrap wood and a hammer to free it from it's calcium prison. Of course, I used my tool to screw in the new one =)

Don't screw in the new eyeball in too tight! Also use some PTFE (Teflon) tape on the threads to make it easier to unscrew in the future.

Note: For commercial use just ask! I want folks to ask permission so I can know where it's being used.

The bigger the layer height the stronger it'll be. I used a 0.25mm layer height, six perimeters, and 25% gyroid infill for mine. If I had a bigger nozzle I'd go with even thicker layers for greater strength.

Shove it in there and turn. Righty tighty and lefty loosey!

Just in case you were wondering if the pool eyeballs have reverse threads: They don't. Both the outside and inside threads are "normal". Nothing funky going on in there.
