Team Crank presented 4 concepts for oil containers: 1. Cheetah - Takes design cues from a cheetah's curved back and claws for grip. Wide sticker areas allow for branding. 2. Atlas - Smooth, minimalist design with separate areas for handling and branding. A void area provides support and torque for pouring. 3. Twheel - Inspired by the robustness of a tire, with serrations that indicate oil level and provide a distinctive grip. 4. X1D2 - A futuristic, clean design that can be easily manufactured. A flat top assists with stacking and durability while pouring.
