The Braun Duo lighter was released on the market in 1977. It was designed under the leadership of Dieter Rams, based on his 'less but better' philosophy.
The lighter was modelled in Fusion 360 and the preview renders were made using Keyshot. A lot of effort went in to making sure that the lighter is as close to reality in terms of its dimensions. The textures shown in in the preview renders are not included.
