Overall construction based on "Barrel Drinks Dispenser 4 Glass" by Seb16420
I made my version a little bit smaller and simpler design, which means it is easier to print - you can print without supports just fine.
Also included version with solid base for printers with weak cooling fans
I recommend PLA, skin thickness parameter should be 2x-3x of extrusion width (0.8 or 1.2 for 0.4 nozzle)
Don't forget to remove all strings and plastic parts, wash strongly before use.
To use pour your liquid in center of cone slowly.
