What would likely help that even more is to do it in some larger spools (say 20kg spools) so that you can do larger runs and then chop it up later. There is a possible market here to do that, but I don't know what kind of margins you could expect; I've got no idea what the power the filament extruders use. I'll know when/if I finally get my filabot from the kickstarter, it's a very very similar design to lyman's but came a bit later. The main thing I'm after for it is that it'll come with a grinder to let me take things like plastic bottles and try to print with PET plastics and other strange materials.
