Basically: A drain funnel lid for a standard five gallon bucket. The lid is a bit nonstandard though. It's an inverted funnel as to flip the bucket and drain the contents. The end of the funnel must have a push-pull valve. The end of the funnel, and the valve outlet, must be 4.5 inches in diameter (2.25 radius). It'll have to be printed in segments, so m4 bolts must be placed on the outside of the funnel to prevent corrosion, and keep a smooth inner surface. Dimensions: Approximately 12" in diameter at its widest point, and 4.5" in diameter at its narrowest. The height or depth of the funnel is 3". Budget: $20 - $40, I suspect an experienced designer can create this in 30 m to 60 minutes. Other important notes: This will be used with a slurry of dirt and water. It will have at least one segment printed transparently. It will be printed with a resin printer.   submitted by   /u/OneArmedFarmer [link]   [comments]
