Drag in a photo, see it in 3D instantly. Pay once, download forever — no subscription, no watermark, no account.
I lost an afternoon trying to turn my kid's drawing into a 3D-printable file. Every tool was either $30/month, broken, or wanted a cut of every download. So I built iGrinder.
Drop an image. See it in 3D. Pay $9 once. Get the file. No account, no subscription, no royalty. The mesh is clean — manifold, watertight, with proper walls and a flat base. Slice it tonight. Print it tomorrow.
If you want to push further, open it in Blender (decimate, smooth, boolean-cut, add base text), then slice in Cura, PrusaSlicer, or Bambu Studio. That's the whole loop.

Photos that come alive when backlit. Use the Lithophane preset, print vertical in white PLA, drop an LED behind it.
Embossed nameplates, business signs, branded coasters. Use Emboss preset for a 1–2mm raised mark on a thick base.
Topo maps, floor plans, building elevations. Drop a heightmap PNG and get a real, dimensional model.
Turn a photo of a person, pet, or anything you love into a tactile relief. Use Cut to Subject for a clean silhouette.
Custom D&D bases, board game pieces, faction crests. Negative-deboss for inset details.
Tessellating wall panels, decorative tiles, modern bas-relief art. Print, paint, mount.
Drop a 2D image. Get a manifold STL. Open it in Blender to refine — boolean-cut, smooth, add text, decimate. Export to Cura, slice with the right preset (flat for relief/emboss, vertical with brim for lithophane), save the G-code, print.
