Let me show you how I built a hand-cranked shredder for recycling plastic waste. I want to use the shredded material to 3D print new parts from it. The shredder was sourced from the Precious Plastics Bazar and delivered as a box of sheet metal parts. Assembly was quiet easy only getting a proper hand crank was a challenge. I ended up with a 80cm long 25x25mm steel tube that is attached to the shaft via a laser-cut adapter. Similar particle size is very important during the process so I designed stackable and 3D-printable sieves that are used to obtain the different particle fractions.
