Different thickness for top and bottom fingers

[dizcza]

I need to glue a 1.5mm thick PCB board to a 4mm thick wooden box designed in Boxes (previously I used OpenScad and lasercut toolbox. I like the rendering routine but the toolbox is limited and finger joins are not symmetric - that's why I'm switching to Boxes).

I just ordered a PCB with the following edge cuts:

Now I need to finish the corresponding wooden parts:

Same for left, back, and front.

I modified the draw_finger function of the FingerJointEdge just to give you an idea of what I want:

class FingerJointEdge(BaseEdge, FingerJointBase):
    """Finger joint edge """
    char = 'f'
    description = "Finger Joint"
    positive = True

    draw_num = 0

    def draw_finger(self, f, h, style, positive: bool = True, firsthalf: bool = True) -> None:
        print(self.__class__, self.draw_num)
        t = self.settings.thickness
        if self.draw_num >= 3 and isinstance(self, FingerJointEdgeCounterPart):
            h = 1.5
        self.draw_num += 1
    ...

This solution is quick and dirty. How to do it properly?

Related to #109 but I don't want to revive a 5-year-old thread with no comments... Besides, I need only top fingers to have different thicknesses, not all / inner layers.
