Overengineered bong pipe for weed NO SUPPORTS!

Well well well, here I am after several days of reiterating the same thing and about couple of coils of plastic wasted, this thing finally works as intended.

It is designed for a 14mm glass pipe and has 3 filters before the main chamber and a turbine of 6 pipes right after. You may want to put some cold water/ice chips in the filters and close them with caps, then pour some water in the main body and you are good to go.
I do recommend to try it just a bit at first in order not to get completely stoned :)
Along with calculated flows functional design which looks awesome by itself, the thing has a bit of artwork in the middle ^^

please add your comments and suggestions!!!

main: 240C PETG, 3mm shell, infill does not matter since the whole model has 3mm thick walls. You may want to tweak the temp for your filament for adequate flow and overhangs. Also retraction settings matter to avoid stringing and not to spend an eternity with a hotgun fixing them. NO SUPPORTS!!!
about 150x150x210mm 13.5hrs with a bit boosted printing speed
cap: 230C TPU. 1.2mm shell, 20%infill. Nothing fancy with them, however I recommend to orient the model on a bed in a way that the tension force while opening happens will be oriented along the layers, otherwise you may rip it apart between the layers, there is a pretty tight fit for hermetical reasons.
about 40min for all three.
