- Download and print the following parts for the Archipelago PET filament extruder.
*Recommended 50%(or more) infill for the gears and left frame section. Other printed parts can be printed at 20% infill.
The files can also all be downloaded from project collection at Tinkercad:

- Cut two wooden boards to size:
- Buy (or find) the rest of these parts.

*Redrill .04mm hole in the extruder nozzles to be 1.75mm.
**Grind a cone shaped cavity into the heating block, while still leaving threads so that the extruder nozzle can attach to it, and then fit the sensor and heating resistor into the heating block.
***If you find alternative parts or buy from different suppliers, make sure the dimensions and specifications are the same as the parts listed.

- Using a 110/220v power cable, strip off some of the plastic insulation so that 20cm of the three wires are exposed. Connect the ground (yellow/green) wire to the power supplies port that is marked as ground. Connect one of the other wires to one of the power supply’s 110/220v input ports. Cut the remaining wire about halfway, connecting the two halves to the two connectors of the switch, and then connect the remaining end to the last of the power supply’s 110/220v input ports. Check to see if it turns on, and then turn it off again.
- Wire the motor to the PWM, and the PWM to one positive and one negative 12v port of the power supply. Turn on the power supply, and then turn on the PWM to check to see the motor is working, and then turn everything off.
- Wire the thermocontroller’s positive and negative ports to the same positive and negative ports being used by the PWM. Turn on the power supply to check to see if the thermocontroller is working - it should show an error message.
- Connect one wire from the thermistor to the thermocontroller’s port marked “relay”, the other wire from the thermistor to one of the remaining two 12v output ports on the power supply, and then a final wire to connect the final port of the relay on the thermocontroller to the final output port on the power supply.
- Connect the two wires coming from the temperature sensor to the two remaining ports on the thermocontroller.
- Test to see that all of the electronics are working properly before tying all of the wires together and to the extruder frame, and then screwing the faceplate to the boards.
- Turn on the power supply and PWM to make sure the motor is turning the correct way - if looking from the left side of the filament extruder, the big gear bobbin should be spinning clockwise so that the filament will be pulled to the back of the machine before being pulled down and then back towards its interior.
