Knife Handle - from scan image

thingiverse

Scan the blade using a basic scanner without 3D capabilities. Load the scanned image into your preferred 3D modeling software, such as Moi 3D. Rescale the image to accurately match the dimensions of a real knife, which can be the most challenging step in the process. Create an outline of the knife shape. Extrude the outline to create a solid three-dimensional model. Add a fillet to smooth out any sharp edges or corners. Drill holes into the design as needed. Use a mirror tool to create a symmetrical duplicate of the original design. Add holes on one side for screw heads and hex-shaped holes on the other side for nuts. Finally, send the design to a 3D printer to produce the finished product.
