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..

All this stuff costs so much because this is a specialised equipment. It is sold at low volume and to keep the business afloat manufacturers have to charge a premium.
