Could you share the file with me if you end up doing that other design? I’d love to try it out too.

- jstanley 8y agoHere you go: https://incoherency.co.uk/interest/pythagoreancup2.stl https://incoherency.co.uk/interest/pythagoreancup2.stl And a 50% opacity view: https://img.jes.xxx/2005 https://img.jes.xxx/2005 The first cup took 90 seconds to drain about 200ml. The cross-sectional area of the tube in the second version is about 4.7x larger, so if my beginner-level understanding of Bernoulli's principle is accurate, I expect it to drain about 4.7x faster, so maybe it'll empty itself in 20 seconds instead of 90.
- jstanley 8y agoThis one drains in 12 seconds, but only contains 150ml due to the reduction of the inner diameter at the bottom. The average flow rate is 12.5 ml/sec vs 2.2 ml/sec before, so it's 5.6x better!
