Drop an STL, OBJ, 3MF or SVG anywhere on the page or click here to browse — nothing is uploaded

Bottom edge

Export format

Drop a flat extruded model (STL, OBJ or 3MF), or a flat SVG to extrude then round in one step. SVG units are read at 96 dpi (1:1 with Illustrator exports) unless you fit the longest side. Radius wider than a stroke closes it into a smooth ridge — thin tapered tips stay clean. Zero-thickness slivers and open (stroke-only) paths are auto-closed or dropped. Download the result as STL, OBJ or 3MF.
