I have those same suspenders.
Man 3D Prints Himself An Entire Outfit

With enough 3D printer filament you print just about anything, and that’s exactly what Youtuber Matthew Trahan did, using 8800 grams (19.4 pounds!) to print himself a complete outfit including a colorful vest, Minecraft style shorts with belt, shoes, hat, sunglasses, and bag. No underwear. You ever tried wearing LEGO underwear before? You’d know if you have, it’s not something you’d forget. It’s not like an anniversary. Everyone forgets anniversaries, right? You mind calling my girlfriend and telling her that? The printing took over 560 hours, which is over 23 days of nonstop printing. That is a long time. I could sew you an entire suit the old-fashioned way in that time. Way less if you’re cool with a birthday suit.
