Here u can see 4 models of the same tracery of ludwig's holy blade from bloodborne cosplay. It's about 1480mm heigh and 145 mm width. Scale it the way u need it. 1 model - its only tracery. 2 model - its tracery with substrate (enable for printing). 3 model - its the same as previous but with hitch for holding tracery in body of sword. 4 model - its the same but with anti-deformation deepening. U need to cut the model and print it vertically for best resolution of tracery. If u will print it with ABS better to cut model to lower height parts for reduce thermal deformation. Tip of tracery is not pretty much with ludwig holy blade, because we had not sketch in good resolution.
Print it vertically. If u want to make illumination under the tracery set infill to 0%. I used half-transparent ABS plastic. My model has hight thermal deformation of edges in printing process. Reduce it by cutting model for smaller (in height) parts.
