Almost no manufacturers want to focus on classic car spare parts because the production volumes are too low. No manufacturing technology is cost-effective enough to bridge that gap, except 3D printing, which is an excellent opportunity for all classic car lovers like OctoClassic. Finding new parts suitable for 3D printing became their hobby and mission. There are plenty of parts in cars which are either difficult to find on the aftermarket or costly. This is the scenario that happened to the classic Mercedes owner who needed to replace the power steering fluid cap, which is not available on the market.
