Here is a model I have produced of a top hat dust separator in Fusion 360. It is inspired from a design I saw on Youtube (search for “panaxion”). I have not tried making this as I don’t yet have an X-Carve and probably wont for a while, I decided to get married instead - an expensive business. If anyone wants to make this or see the Fusion 360 project let me know, I would be happy to share it.
Thanks to the paramerised nature of Fusion 360 the model is easy to modify for different inlet and outlet sizes and material thickness. There are a few other parameters that can be modified too to suit your bin size and overall dimensions.
There is a little work still to do to get it CNC ready. It looks as if there are some good add-ins to help with the final things. Id look at dogbone to get the corners of the mortices milled out and nester to get the pieces laid out flat.
Beware I’m a fusion 360 beginner and this is the first model I have produced other than one or two tutorial tasks from the documentation.
