Dark souls Estus Flask with screw on top.

thingiverse

The Estus Flask, a design inspired by the Dark Souls series, comes in two versions - smooth and textured. Both models have undergone rigorous leak testing for over a week, ensuring their integrity. The container holds approximately 6 ounces, equivalent to half a soda can. When resizing, users can scale up as desired; however, scaling down may compromise the structural integrity due to thinner walls. To achieve a secure seal, the threads are designed to be very tight. Those who prioritize a snug fit can resize the top by 2-5 percent less than the bottom without compromising the design. Print Settings: Rafts: Ignore this setting. Supports: Disable them. Resolution: Opt for the highest available resolution. Infill: Set it to 100% to ensure maximum structural integrity. Notes: For storing liquids, it is highly recommended to set infill to 100% and shell thickness to at least 1.6 mm to prevent leaks. While a raft can help with adhesion, supports are not necessary as most software will generate them internally.
