Simple Funnel - Customizable/Parametric

It’s a funnel. That’s it. No hidden compartments, no secret storage, no Wi-Fi, no subscription plan. Just a humble, hard-working funnel doing what funnels have done since the dawn of time: moving stuff from “too big” to “fits now.” Pouring oil? Great. Refilling birdseed? Perfect. Pretending you’re conducting a science experiment in your garage? Go for it. This funnel won’t judge — it’s just funnel.CustomizationWant it bigger? Smaller? Wider? Narrower? You’re in charge. Adjust the bottom diameter, slope, wall thickness, and height to make the perfect funnel for your needs — from espresso precision to bucket-sized ambition. Just tweak the parameters, hit print, and watch your personalized funnel come to life. Note on the diameter: I designed this so you can pick the outer diameter of the lower part. The inner diameter will be smaller (by the wall size * 2). I did this intentionally so that you can set the size to be the size of the opening you want to put this funnel in.
