Hi Tim! Thank you for the comment. I made a mistake when I changed the font format. Sorry for that! I have readded the letters in the last release (0.6.1).

Hi is there a way to reverse the slids so they go from top to bottom instead of bottom to top? And make a certain Y or X follow a curve instead of just X or Y?
Use a reversed base plane (z-axis negative) to reverse the slits.
Use the Slice component to define a custom slice pattern via planes.
