So, I designed these for myself to extend my IPA (and recover Resin) and they’ve been working very well! Now I am hoping to print them for others to help fund my expensive resin-habit! 🙂 [Platform “Drip-Dry” tool](https://www.azproductworks.com/products/drip-dry) [Cartridge Coupling](https://www.azproductworks.com/products/coupling) Anyway, check them out and let me know what you think! _PS: The site will give you a 20% off when you use the “bundle offer” combo on either page._ ![Screenshot 2022-03-26 105733](https://us1.discourse-cdn.com/flex025/uploads/formlabs/original/3X/e/b/eb907ace68a5110625dbffd4d4b88dd67236804a.jpeg) ---

Interesting. How do you keep the bite valve open to transfer the resin? ---

In this case, it is not necessary keep the bite valve open. The hole of the screw cap is large enough. ---

So what am I looking at here, emerging from the upper cartidge? ![Captura de pantalla 2022-03-29 a las 17.41.43](https://us1.discourse-cdn.com/flex025/uploads/formlabs/original/3X/5/0/503b72d7f780f25e42325944bc3f9a1511dd26fc.png) ---

Generally the cartridge being drained is about to be discarded (not reused). I simply pull the rubber bite valve off of that cartridge and open the cap so it can breathe. ![Screenshot 2022-03-29 091329](https://us1.discourse-cdn.com/flex025/uploads/formlabs/original/3X/7/e/7e9099dd0d16f69719b3d002d7f6c3d0392015c6.jpeg) ---

those little ribs are part of the cartridge itself, they sit on either side of the bite valve (what I show there is what you’d see once the valve is removed). check out my visual reference pasted in another reply ---

Ahhh! Remove bite valve, that explains it 🙂 Btw selling the stls should help you economically too. ---

Unfortunately I ran in to trouble on a different product when an overseas buyer I sold my STL to, began printing and selling my own design against me. That was a hard pill to swallow. ☹ ---
