This is a cyclone vacuum cleaner. It's work with a 2.5A, 12V computer fan. For best aspiration you can change fan.
I made this for work with my Proxxon TG125 disk sander.
For best safety, you can add at the top of fan a finger guard.
I have created another adapter to replace the fan by a 12V Bosch Vacuum Cleaner. you can find the thing right here: https://www.thingiverse.com/thing:2437874
<= If you like my work, you can tip me on Thingiverse :-)
To assemble the vacuum cleaner, you can use M4x12mm screws and bolts.
