Compensating for x-y tilt?

Question

I am attempting to 3D print an object, however, I have a tilt in my x and y-axes. I would like to raise my base structure up to compensate for the tilt. Does anyone have a formula that would compensate for the tile and allow me to add a gradient to slowly increase the base by an x-y gradient giving let us say an x-tilt of a degrees and a y tilt of b degrees?

Answer 1

If the horizontal $x$-axis is tilted vertically by angle $\alpha$, and the width is $A$, then trigonometry says that the height difference between the ends is

$$\Delta z_x \approx A\tan\alpha \approx A\sin\alpha$$

Likewise, if the $y$-axis is tilted by angle $\beta$, and the length is $B$, then

$$\Delta z_y \approx B\tan\beta \approx B\sin\beta$$

These approximations are good for small angles.
