Vacuum Turbine Tool 2.0 adjustable with ER11 Shank

thingiverse

Updated Version of an earlier tool. This version utilizes an ER11 shank which has a whole set of collets available for whatever your light tooling needs may be. Necessary changes include increasing the bearings to 8mm ID as opposed to the smaller and requires reprinting the whole thing if you were using an the pprevieous tool with a 3-jay chuck. The ER11 shank solves the balance issues and runs true at all rps. Additionally, the dust nozzle has a recessed track for gluing in some soft bristles from a cheap hardware store paint brush. It's not necessary but I am using this tool for maching sand and the bristles help with dust collection a lot! Links to the shank, collets, and bearings can be found in the instructions. Reference assembled file to see how all the parts come together. Instructions Print one of everything, and 2 of the turbine blade files. I used solid fill at .2mm layer thickness.
