Hayward sand filter drain cap (large filter)

thingiverse

I searched for this drain cap model everywhere and couldn't find it, I only found the small drain cap. I believe that this one's PN is SX180LA. It fits my S166T model. I've printed it using Ultimaker S5 and Tough PLA but you can use any PLA instead. Don't forget to print the gasket, it's mandatory. I've printed it using TPU 95A and used the side facing the glass build plate facing up toward the filter because it's flat and sealed. You can use any TPU or Silicone sheet and cut it to 41mm diameter instead of the printed gasket. It sealed my filter drain perfectly. Updates: I added another version called "Cup". this one needs support only at the bottom. The difference is more visual, you can use the simple version without any difficulties. 24.07.23: I've updated the files (v2.0) and made the tolerance more free.
