I'm 19 and built a 3D marketplace with no creator commission because I was sick of losing 30% — tear it apart
Not going to pretend this isn't my project — it is, and there's a link at the bottom. I'd rather post it honestly and get roasted than dress it up as a "discovery." I've been modeling and printing for years and two things always bugged me: marketplaces take 20-30% of every sale, and there's basically nothing stopping someone from re-uploading your STL the day after you release it. So I built the thing I wanted to exist. What it does differently: Creators keep 100% of the sale price. Buyers pay a flat $1 fee that covers payment processing — that's the whole model, I don't take a cut of your work. Every uploaded mesh gets HiddenMark — a steganographic watermark written into the geometry itself, not metadata you can strip. Public verification, so if your file shows up elsewhere you can prove it's yours. Universal 3D viewer (STL/OBJ/FBX/GLB) so buyers see the actual model before paying. First 100 creators get a permanent "Founding Creator" badge. What I genuinely want: poke holes in it. Does HiddenMark survive a remesh or a repair pass in your slicer? Will the $1 buyer fee scare buyers off? Is "no commission" even sustainable? I'd rather hear the brutal version now than in six months. It's early — small number of creators so far, being upfront about that. Link's here if you want to look in comments
