Hi, I'm
Welcome! I'm Spencer Mann (Spencermann). I'm an engineer by training, and I design and test-print these models at home — often with my kids — on Bambu Lab printers. A lot of my work is Hollow Knight and Silksong cosplay (masks, needles, nails), plus Glitch Productions figures, working water fountains, and everyday utility prints. Every file I publish is free on MakerWorld.
Browse by collection — each category highlights every model in that theme.
