Power Supply 12V 5A
You can use either a 5A or a 10A power supply. The difference lies mainly in the stability of the motor speed and the consistency of the nozzle temperature. A stronger power source allows the nozzle to heat up more quickly and maintain stable performance.
12V (7RPM) DC motor
The motor is integrated into the holder and directly drives the spool to wind the finished PET filament. This 12V DC motor comes with a built-in gearbox, so there is no need to print an external one. Thanks to this, it provides very high torque without requiring any additional gear system.
6mm DC motor shaft coupler
Flanged shaft hub that couples the spool directly to the motor shaft, eliminating winder slippage under load. Install on the winder’s motor shaft as the rigid interface between the shaft and the spool.
PWM Regulator 12V 5A
PWM 12V DC Motor Speed Controller Module (DC-DC 4.5V–35V Adjustable Regulator). This compact module enables smooth adjustment of motor speed, allowing you to increase or decrease it without losing torque.
Heat Block
High-Quality V6 Heater Block, plated copper-brass with PT100 support. Designed as an upgrade part for the E3D V6 hotend and compatible with DDB Titan extruder systems.
Heater 12V (40W)
Ceramic Heater 12V (40W). This component is inserted into the heat block and provides reliable heating of the nozzle. It is a simple and inexpensive part.
Color Switch (230V)
The colored power switch. Always make sure the switch matches the rating of your power socket. If your local mains voltage is 110 V, it is safe to use a switch rated for 230 V — but never use a 110 V switch on a 230 V network!
W1209 Thermo Controller
This simple and cheap controller is heart of PETamentor. It can be alternatively used to control the heat up your nozzle more than you need. But don’t worry, we know how to handle it.
Diode 5408
This small cheap diode allows you to hack the w1209 thermocontroller to bypass its native function interval (only up to 110°C). After aplying this diode you will be able easily reach temperatures over 260°C!
100K Thermistor
A 100K thermistor serves as the temperature sensor commonly used in most 3D printers. You might already have some on your workbench, but if not, don’t worry — they usually come in packs, so you’ll have spares on hand.
Thermometer
To get an accurate nozzle temperature, you need to measure it with an external tool. The W1209 controller will display incorrect values because of the diode hack.
The Nozzle 1.5mm
To convert a PET bottle into filament, I use a standard nozzle with a diameter of 0.4 mm, which must be drilled. Drilling is very simple, using a 1.5mm drill bit. Here is a video tutorial, or you can buy 1.5mm
Metal Bracket
L shape metal bracket (20×20) for mouting a heatblock with the nozzle. Hole is little bit tight, so its better to drill it with 6mm drill bit (only for a nozzle).
