Filter Funnel

I was trying to filter some of my IPA that I had used to clean resin prints and ran into an issue where the filter was plugging up at the tip (using a standard funnel) while the rest of the filter paper was unused. I watched a video by Veg Oil Guy (VOG) on Youtube and he explained this exact issue and actually designed a similar funnel that he used. Taking a page from his book, I designed my own and have been using it in conjunction with a cheap coffee filter and have been having a great deal of success. This was designed in inches, so if it shows up tiny in your slicing software, just multiply the scale by 25.4 to convert mm to inches. Let me know what you think and POST THOSE MAKES!
