Flask Cork/Stopper

Created a custom cork stopper (~38 mm max diameter) in Tinkercad to fit in my Erlenmeyer flask as part of my mad scientist costume. I created a stopper with no hole, one with a 6.2mm diameter hole, one with two holes (6.2mm diameter each), and one with two different holes (6.2mm diameter, 11mm diameter). The latter is the one I ended up using to fit the tubing inside my flask for both a dip tube connected to my mask for drinking and transfer tube from my "radioactive" tank.
