Spencer Mann — 3D Printing Designer

I publish free STL files on MakerWorld as Spencermann. This site is my catalog of 100+ designs.

Who is Spencer Mann?

Spencer Mann is a 3D printing designer who models, test-prints, and shares free files on MakerWorld (@spencermann). I am an engineer by training and print at home on Bambu Lab printers — often with my kids — before releasing each design.

If you searched for Spencer Mann 3D printing, you are in the right place: my MakerWorld handle is Spencermann, and this website lists every model with photos, descriptions, and download links. My most popular work is Hollow Knight and Silksong cosplay (Hornet Mask, Hornet's Needle, Pure Vessel, Zote, and more), plus Glitch Productions figures, working water fountains, and everyday utility prints.
