Summary I created this PVC funnel to solve a real-world problem: Normal funnels aren't long enough! I needed a way to pour boiling water into our home's clothes washer drain to clear out detergent buildup (someone's been using too much!). Because the drain is in a tight spot it's all but impossible to pour a pot of boiling water (slowly) into it. Normal funnels are either too wide to fit into the cavity above the drain or their spouts are too skinny/short (e.g. "ain't nobody got time for that!"). Using a length of 1/2-inch PVC pipe solves this problem entirely but taping a funnel to the pipe never works for long (at least, not with boiling water!). Hence, the custom-made PVC funnel. It should fit nice and tightly around 1/2" PVC pipe and has an internal taper to ensure nothing leaks; no need to cement it! I tested it with SCH-40 PVC but SDR-21 (thin wall) should work too. Note: I uploaded a transparent render of the model so it would be easier to see the internal taper and how that works. Print Settings Printer: Original Prusa i3 MK2 Rafts: No Supports: No Resolution: 0.2mm Infill: 25% Notes: Any resolution should be fine, really. Infill probably doesn't matter since the model is mostly just perimeters. Just make sure to print it in something that can withstand boiling water (e.g. PETG) if you plan to use the funnel for that purpose (cleaning out washer drains). No need for supports! It should print just fine without anything fancy.
