plastic recycling machine 3d model

Design a horizontal machine that recycles plastic into 3D-printer filament. Linear workflow and all recycled parts: potato shredder → extruder → sheet spool or extruder → size control → cooling → puller → spool winder. The shredder has a top slot and two gears; the extruder has a heated barrel with nozzle and small display; the size controller has an adjustable circular opening; the cooling unit is a small tunnel with water the puller uses two pulleys and a motor; the winder rolls filament on a spool. Clean, educational, simple geometry, 60×20×20 cm, mounted on one base plate
