I forgot the painter did spray a base, he used black to accent the scale separation.
All my toys and no 3-D printer yet. Really want a desk type water-jet but they are $$$. A plotter would cut a 2’-3’ wide by up to 75’ or longer Mylar template. We used them to layout real high end granite cuts for millwork and what not. I tried buying one at an auction but sealed bid and I was too cheap.
If someone (not me) was real crafty they could do some cool stuff with auto detail/painting tapes. I’ve some real thin stuff floating around but zero talent.
