Learning how to use the "Revolve" function in fusion360 to create new designs and the Flasks here are the results. The mindset is to think of splitting the model in half and design the outline of onside and then us the revolve function. I created these using Fusion360 and export to STL and printed on the Creality K1 and K1C, using Creality Hyper PLA.
The author marked this model as their own original creation.
