If anything screamed out "3D print me" then this model would be it. With each of those indentations 0.8mm you're going to need an awfully tiny bit to get those inside corners even close to "square".

This is closer to your design. You were right about putting things on different layers. Hopefully you can understand the process I was using. The original vectors from the DWG file are in layer 0. I copied them to different layers and cleaned them up for machinability. The V8.5 CRV file is attached.

Please ask questions and show us your progress.

Question 1: Isn't the pass depth for the ThruProfile a little too much? 5.625 mm for a 2 mm dia. bit. Ditto for the StandoffPocket. Unless the material is foam.

Question 2:Does the 2mm end mill get fatter above the cutting portion? If it does I would check for interference with the standoffs and lip while cutting the ThruProfile and StandoffPocket. Easily fixed by making the standoffs round and making the lip (and material) a bit larger.

Question 3: Why the LipProfile toolpath? That edge is also cut by the StandoffPocket toolpath.

Question 4: What does the STL in the title refer to? I don't see any .STL files here. Nor would I expect to for this type of project.

Note: Spaces are permitted in toolpath and Layer names, if you so desire.

I suspect my questions are just covering things that ordinarily would be fixed before cutting.

Good questions/comments Mike. And as adze_cnc noted, this particular design might be better for 3D printing.
