Here are the legs for the landing pad in SketchUp:
And here is the full model with the legs, top and bottom view:
Once I have it all modeled in SketchUp, one of the big challenges is converting that to a file I can actually cut using the laser cutter.
What I usually do is "flatten" each component in SketchUp, and then place them on a flat surface that is the size of one sheet that I can cut (12" x 24"). In this case, I ended up with three sheets (one of which would be cut in thicker material for the inlay):
Once I have this in SketchUp, I save it as a PDF and then import it into InkScape, where I can change the line thicknesses, make some adjustments and re-save it as a PDF for printing (cutting).
