They totally work. Here's a good video
@khird The fgc9 in the video is designed to be printed on an ender 3
@valleyforge Yep, that looks a lot nicer than my Printrbot Simple V1. I'd still want to do a lot of test prints to gain confidence in the print quality though.
@valleyforge I don't doubt that they *can* work if printed on a sufficiently reliable and precise machine! But my printer is neither of those, so I'd be buying the finished print from someone else - which kind of defeats the purpose.
