So if your curious what 526 means. thats why.\u003c\/p\u003e\u003cp\u003eI own an ActiveAqua Submersible pump and I lost my other adapters for it . I searched everywhere to buy some adapters and I couldn't find the correct ones for my pump!\u003cbr\u003eSo, I bought a cheap pump on Amazon... Sadly the 1\/2\" or .51 barbed was a touch too small.\u003c\/p\u003e\u003cp\u003eI decided to copy the adapter with 3d printing characteristics. I made the barb .526 which fits perfectly!\u003cbr\u003eHowever, the threading was much harder to find. \u003cbr\u003eI started off with 3\/4-16 by counting the threads; about 14 to 16 per inch. Didn't fit!\u003cbr\u003eMaybe it was Metric? The thread pitch was 1.8mmish which looked odd but maybe I was measuring it wrong? So I printed both M20 1.5 and 2 pitch. Correct size but not correct thread.\u003cbr\u003eAt a loss, because it wasn't 7\/8\" I didn't' know what to do??? until I figured it out. It was an M20 with 14 threads per inch. YES A MIX of both metric and US measurements. \u003cbr\u003eAlmost perfect... it was a bit lose\u003cbr\u003eSo 2A means loose fitting; which still tightens onto the pump. and 2B means tight. Its tight!\u003c\/p\u003e\u003cp\u003eHopefully this helps someone.\u003c\/p\u003e\u003cp\u003eI spent less time making sure the other threads were correct. Mostly trying to find out what my pumps threads were. So, if your pump has a real M20 or 3\/4-16 thread and it doesn't fit perfectly. I have included the CAD files for you to change it a bit.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eI printed this on my Prusa MK3S with a .4 normal nozzle and .10 fine detail PETG. Also think about using a tiny skirt to keep it on the bed if your having a hard time keeping thin prints stuck to the bed. \u003c\/p\u003e\u003cp\u003eDesign by machina_sculpto on MakerWorld (license: CC0).\u003c\/p\u003e","brand":"Mymadmanlab","offers":[{"title":"Default Title","offer_id":67444033749296,"sku":null,"price":6.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0987\/0809\/5280\/files\/0_cf0ac4b1-ddcd-4aa5-92c0-40ecbc7a432b.jpg?v=1785794965","url":"https:\/\/mymadmanlab.com\/products\/1-2-barbed-adapter-for-cheap-submersible-pumps","provider":"Mymadmanlab.com","version":"1.0","type":"link"}
