French handyman and inventor Bodet Ludovic was in need of a good way to make an O-ring, and in the process, ended up creating an ingenious new product called the EasyWelder. His tool offers a way to save 3D printing filament--and money--so that if you have a bit left over on a filament spool, you can use the tool to weld filament pieces together. EasyWelder is also helpful for 3D printing large parts, and it allows you to do things like 3D print easily with multiple colors and materials. The EasyWelder from Ludovic and the I3D Innovations team will be available if there's interest. Check out more details in the full article: http://3dprint.com/66283/easywelder-filament-weld/
