About this 3D model

Overview: This is my version of machine to recycle PET bottles to filament for 3D printer. Here you can see my setup with two units in operation.

The termocouple should M6 mounting screw. 1x DC Motor Speed Controller (i.e. Speed Controler 5A ) Feet 4x Foot.stl 1x Foot_template.stl (if you want to predrill the holes for screws) 4x Rubber pads 40mm diameter 12x Screw 3.5x20mm Other (Optional) 4x Corner_Protector.stl 4x Screw 2.5x12mm 1x Handle.stl 4x Screw 4x25mm Notes: For the spooler I have used M5x100mm screws with flat head which were easily available in hobby market and I have designed the spooler moder for these screws. If you don't like these screws print Spooler_Side_Right_B.stl and use other screws or threaded rod. If you don't have capability to manufacture heater block according to the drawing you can use for example V6 Heater Block mounted on L-shape holder from hobby market. In this case buy K type thermocouple in small package not with M6 mounting screw. Electronics: I use power supply voltage 24V thus thermostat, motor, cartrige heater and fan are 24V version. If you want to use supply voltage 12V order appropriate version of these component. I use power supply which is cabable to deliver 10A current which is more than enough for two units. 3A current should be sufficient for one unit. Accessories: For cutting the PET strips from bottles you can use my Simple PET Bottle Cutter or PET Bottle Cutter with Bearings . For storing PET strips you can use my PET Strip Spooler And Spool Holder .
