Just a quick post to share a site that lets you create custom 3D printed sword handles – https://powerful-sands-30060.herokuapp.com. Once you enter the measurements and taper of your tang, the site outputs a file that you can take to a 3D printer (provided the printer can make objects that large). You could also send the files to one of the many online printing services if you don’t have access to a printer.
Thought I would share, took quite a bit of online searching to find this so I wanted to do my small part to raise awareness of a cool tool.
