Does any of you have any experience with this? I’m looking at the Felfil Evo pellet extruder which seems like an acceptable option. One thing I don’t understand. Why are the shredder and spooler so ungodly expensive?

I mean, can’t you just use an old blender to grind pieces down far enough for the pellet extruder? The finer the better no? Airborne microplastic may be a concern at some point.

Also the spooler. Is that more complicated than a stepper motor that runs at a certain RPM spinning the spool around? With perhaps a mechanism that slows down a bit after X rotations to compensate for the spool getting thicker. Nothing an Arduino can’t handle. Also don’t grip the spool that tightly so pull strength is more or less equal.

Both the spooler and shredder individually cost more than a pellet extruder does…

    I would love for a small business to have one near me. I would literally give them the scraps for free. I’ve just been saving the chunks in a bin

      I think in most cases you have to pay the price of postage. Some of the companies will offer you an incentive like free or discounted spools of recycled filament to offset this, but the only one I’ve found that’s in Canada with me ( filaments.ca ) does not. Printerior Designs in the US apparently does (never dealt with them myself), and there are a couple in the EU.

        Yeah Id give away all my filament do whatever with it in the name of environmentalism but I’m not paying for a company to sell my off cuts
