Custom Cutter STL Generator
Generate print-ready STL files for custom cookie and clay cutters. No CAD software needed — design and download in your browser. Watertight, slicer-ready geometry.
From shape to STL in under two minutes
No file conversion. No mesh repair. No intermediate steps. CutClay generates clean, printable geometry.
Select a shape
Choose from 2,000+ parametric shapes, or import your own SVG/DXF file (Pro). Every shape is a clean, closed solid — not a mesh of problems.
Set your parameters
Define exact dimensions in millimeters: width, height, blade thickness, blade depth. The 3D preview updates in real time so you see exactly what you’re exporting.
Download your STL
Click Export STL. Your file is generated instantly and downloads to your device. Open it in your slicer — it’ll be clean, watertight, and ready to print.
Why STL quality matters for cutters
Not all STL files are equal. Poorly generated cutter STLs have non-manifold edges, inverted normals, or gaps in the mesh that cause slicers to produce unreliable toolpaths. The result is weak walls, missing sections, or prints that fall apart after a few uses.
CutClay generates STL files from parametric geometry rather than mesh manipulation. Every exported file is watertight, manifold, and correct. It opens cleanly in PrusaSlicer, Bambu Studio, Cura, and every other major slicer without repair steps.
The free tier includes 3 free STL exports (lifetime) from all 2,000+ shapes. Sign in with Apple, Google or email (free, one click) when you’re ready to download.
