Here's a design I worked up for somebody on etsy for Cloud Strife Wolf trailer hitch cover from Final Fantasy VII.
I designed it from scratch, then printed on a prusa MM using matterhacker red, black, and glow in the dark for the eyes.
I designed it with as little use of the purge tower as possible, with a closed border to hide the actual color depth of the veneer. This way it uses as little material (<5g waste) in purging between colors. Once it hits 1mm layer height it stops purging altogether as the rest of the object is a single color.
The GitD didn't have enough mass to really glow, so if you make a copy for yourself I'd say white would be the best color.
Like the design and have some ideas of your own? Hit me up at www.3dprinteddebris.com and I'll see what I can do. This one was $40 all up, which included 2 reviews of the digital design before committing to printing.
