I bought a bench sander with grinding wheel and sandpaper, after the first uses I realized that working in the part with sandpaper made a lot of dust, so I made this collector to attach to my vacuum cleaner.
Printed in ABS, 1.2mm wall thickness with the hose for the vacum cleaner on the top. Feel free to find the best solution for you.
The hose of my vacum cleaner is 35mm of diameter.
In my case I drilled one of the two sides to insert a flat head screw. I tried to make it as universal as possible, so you'll have to find the best fixing system according to your tool.
