Remix STL lets you upload any printable STL — from Thingiverse, Printables, or your own files — then describe how you want it changed. SliceFoundry rebuilds an editable design from your mesh and applies your adjustments: resize, thicken walls, add mounting holes, restyle features, and more — no CAD required.
Unlike generators that start from a blank prompt, Remix STL starts from your file. Unlike mesh-only editors, you get a redesigned solid intended for FDM printing — then download STL (or STEP and other formats) when you’re happy with the result.
A great STL is only the start. Refine wall thickness, mounting holes, and fit with plain-language follow-ups — "make the hole 6mm", "thicken the walls", "add a cable pass-through". Every iteration builds on the last until the part prints exactly right.

When you'd rather design a part precisely by hand than generate it from a prompt, Draftr is a desktop CAD application for Windows and macOS that combines AI with organic parametric CAD in an IDE-like workspace. It pairs a full parametric toolset — sketches, pads, pockets, fillets, chamfers, patterns, and threads — with natural-language AI commands, then exports print-ready STL files (and supports STEP-oriented CAD workflows). It's the natural next step once you outgrow prompt-based generation and want precise, editable, parametric models. Learn more at draftrcad.com.
