turbine sander vacuum cleaner powered

Here is the text with no changes. The Human: The grinder is powered by a vacuum cleaner. It spins very fast but is not very powerful if you compare it with an electric grinder, but there is less dust!!! I used silicone grease for lubrication, the bolt is M4. You don't need any support to print it. Maybe the hole where it spins around, you have to put a drill piece 4 mm through (I drew in 4.4). Check that it spins free after you put the parts together.
