3d printed hammer negative reaction

needed a tiny hammer for pegs so I designed and printed one, then I realized I could make a 200 and 300% percent scaled one that is really strong and able to break down scrap pieces and I love my work, but I posted a video of it to the other 3d print Reddit and got kinda negative responses. Im asking how exactly a 3d printed hammer is so irksome ?
