About this 3D model

For the recent design competition ran by esso, I have designed a dumbbell which is weighted down by energy drink cans. The 3D printed container holds 3 cans, 1 of them being housed inside the grip. This exercise device can be constucted with already used cans that are filled with something to weigh them down, like sand, or it can be used with fresh cans of energy drink that can then be drank after the workout. This fits the design brief of upcycling while also appealing to esso's brand, a sports drink company.
