T-Cell Cleaning Stand

prusaprinters

<p>This is a cleaning stand for Hayward (or compatible e.g. Blueworks) T-cell salt water pool chlorinators. The way it works is you screw it on one side of your T-cell so that it stands straight up and seals the bottom from leaks. Then you pour in some white vinegar (or your chosen muriatic acid/water combination though I don't recommend that as it can damage the cell!) and wait while it dissolves any lime/calcium build-up inside the cell.</p> <p>Tip: You can use a nylon zip tie to (safely) break off chunks of calcium from the "fins" of the chlorinator.</p> <p>Note: Hayward makes a ~$23 cleaning stand but this stand only costs ~$1.50 (in filament). Also, it prints faster than Amazon can ship to you! =)</p> <p>I've included the .scad files I used to create this stand so you can customize it to your heart's delight. Just note that the threads don't match exactly because Hayward intentionally made the threads on the T-cell proprietary. They're good enough for a stand but maybe not good enough for anything under pressure.</p> <h3>Print instructions</h3><p>Print the stand in your filament of choice (anything will do) at 0.15mm layer height (so the threads will get enough resolution) and print the o-ring in flexible TPU (whatever layer height you want). I printed the o-ring with 15% infill but you might be able to get away with less.</p> <p>Shove the o-ring in the bottom of the stand and it's ready to go! If it leaks you most likely haven't screwed it on tight enough or your TPU material isn't making a good-enough seal (might need a drop of oil).</p> <p>Tip: I recommend "3D honeycomb" infill since it does a pretty good job at minimizing overhangs when printing something like this (the first flat circle can have some internal drooping into the infill on that first layer).</p> <p>15% infill on the stand is<em>probably</em> good enough but if you want to be extra safe I'd go with 20-25%.</p>
