Mirror an STL, OBJ, or 3MF model along the X, Y, or Z axis to make left and right versions of a part. Free, in your browser, with corrected normals.
Files are processed entirely in your browser. Nothing is uploaded to a server.
Any 3D edit is just a prompt away.
Any time a design comes in a single orientation and you need the opposite hand: a right shoe last, a left bracket, symmetric drone arms, hinges, or cosplay armor pieces. Attach the file, pick the axis, and download the flipped copy. Normals are corrected automatically, so the mirrored mesh stays printable.
GrandpaCAD turns a text prompt into a ready-to-print 3D model. Functional parts, organic shapes, multi-color prints. No CAD skills needed.
"Model a symmetric left/right pair of shelf brackets, 80 mm tall, each with three countersunk screw holes."
