Bell siphon (tuned)

Tuned bell siphon based on https://www.thingiverse.com/thing:2119390 (parametric OpenScad). Design is targetting a growbed about 11-13 cm deep and works fine without the bottom cup (see further tuning below). We used 20mm diametrer and 9cm height. Tickness of 1mm for reducing printing time (looks rigid enough).

Model is upside down ready to print.
