Filling in and joining corners

[fsonnichsen]

I couldn't find this issue but perhaps don't know how to search for it. I have a common design where screwed connectors accept screws that hold a base as seen in the attachment. I want to add "fillets" to the cylinders such that these join the planar surfaces to attach them and give them strength.

  I would have assumed I could use a tangent/arc construct but 360 does not seem to accept tangents to circles. SO I used the "Conic Curve" shown in one of the cylinders here and extruded it.  This should be fine but is there a better way/tool to do this that I am missing?

  Also -  is the result shown physically "joined" insofar as 3D printing is concerned? 

Thanks

One way to do what I think you desire is by modifying the sketch before extrusion.  I applied my idea to one corner boss.  As far a 3D Printing, make sure the extrusion is set to "Join" the body.  This will allow the feature to print as part of the main body.  Model is attached.

OK-that was a big help. I had actually done the thing with circles but did not remember that the "cut" would work that way. And--yes-on the join. A good technique for a lot of situations.
