How to impress with a trapeze form?

[nohkumado]

Hello,

don't know how to ask differently than to post an issue :(

i am using this great tool to impress a logo on a case, but since i don't have a double extruder, after printing, i fill the imprinted holes with paint....

works at first, but after a while the paint begins to fall out of the imprinting.....
BTW i am still a beginner with openscad....
so, what would be great, would be to extrude with a scaling, so as to have the base of the imprinting larger than the hole at the surface, making it harder for the paint to fall out of the whole when the cohesion between pla and acrylic paint fails, but whenyou scale and translate, well, the result is not what i hoped (i tryed to parametrize the scaling factor that is set to 100.0) ...

so is there a way?

thanks for maintaining this tool, and having the image as a module is a great addition to the initial tool!
