I would love to re-use my failed prints by re-extruding the plastic to be used int he 3d printer once again. One thing that stand in my way is finding a effective way to shred the plastic into smaller bits for the extrude to use. What is a good thing to look for to accomplish this? Maybe a really big 'paper' shredder?

there is a project called precious plastic and there is a plastic shredder, but it is a rather expensive solution.

As I am waiting for parts for my Lyman extruder, my plan is to hammer the parts and then process in old kitchen robot with steel working area, an example here

The paper shredder will be ok as long as you can feed it with plastic.
