Dust extraction adapter for Proxxon DSH 230

On Scroll Saw I always find a blower to clean the cutting area, but I don't find this system efficient because it spreads the dust in the environment. To solve the problem, I designed a system that provides for aspiration from below on the existing arrangement and from above with a new tube to replace the blower. Both tubes are connected on a main tube that fits into the laboratory aspiration system (diameter 50mm). The hose is 32mm internal and 40mm external. https://www.bricoman.it/it/tu
