After going thru similar adventure I can recommend few things, first is 1.6mm MIG nozzle, works far better than any diy nozzle i did and requires no drilling at all. Second, you can automatically cut the bottles while spooling, it saves tremendous amount of time, no need to pre-cut entire bottle, just make bearing cutter. Blade cutters are terrible. I have couple of vids on my channel with my machine. You have issues with 200 deg because your nozzle has not enough hot zone length, this is why imo its bad choice. Mig nozzle is very long and has very long hot zone.

after printing, heat the 3D printed part for few seconds just a little less than melting point. It will smoothen the layers and overall appearance.

Brilliant project I just happened upon, I am just going to start ordering all the parts. As a Diabetic I drink over 2 litres of water every day so have an endless supply of clear bottles, many thanks for all the effort you put in to create this project. All the best Stuart

A very cool build! Some thoughts: 1. To quickly cool down the filament, you can pass it through a 2mm brass tube that goes through a water tank. 2. To automatically set the winding motor speed--and, therefore, the filament thickness--I would have the filament exit the brass tube and travel between two bearings, with the top one mounted to a long, sprung arm (to act as a multiplying lever) that has a magnet on the end affecting a Hall Effect sensor, which reflects the distance between the bearings. The Arduino can then set the motor speed by the signal sent by the sensor. A series of shims placed between the bearings can be used to train the Arduino. 3. A 'spot welder' would be useful for joining strips. It wouldn't need to be anything more complicated than a couple of heaters with split PTFE tubing wrapped over their ends--to prevent sticking. 4. A 'rope making machine' (like this one: https://youtu.be/25mmaiZ_gGk ) would allow turning very thin strips of PET into strong cords. A nozzle drilled out to the desired cord diameter would smoothen the surface. As well, such cords can be made of different colours for multi-colour filament. 5. An enclosure for your printer--even just a cardboard box!--would help maintain temperature. Cheers!

For pulling the filament you want to be doing it at 210c. From a bunch of testing we found print settings of 0.2mm layer height, 260c nozzle, 75c bed, initial flow 130%, flow 130%, print speed 30mm/s, retraction 4.5mm, retraction speed 40mm/s, fan speed 15%. Any other questions feel free to ask

This is a great solution to recycling plastic bottles. My misses must get through 8 2lt bottles of water every month and I've been thinking about how I could turn that to my advantage, when it comes to 3D printing, I've seen many videos pop up on here on the subject, but never watched any until now. What an ingenious solution to the problem. Gotta give it a try.
@serovsergey5888
For a long time I have been printing only with home-made filament from bottles)) Thanks for the electronic diagram and sketch!! I will definitely collect and apply in my machine! You need to print at a slow speed - 20mm / s then the plastic will have time to melt. And the printing temperature is 270 degrees..
@Benegade
This is such a cool environmentally friendly idea
@thealgerianman7275
FINALLY , you talked about this interesting topic i have been waiting for this video Glad you made it ❤️
@jasenking4092
I have ordered all the parts from AliExpress and Pcbway. I am going to start a video today of me assembling your invention. I printed all the parts int PETG. I left your name on the spool holder parts. Thank you in advance for all the work you put into this I would have never figured all this out on my own. I am a little intimidated by building the board.
@grantfielder
Just placed an order for your PCB ma dude! Can't wait to get it going when they arrive. Thanks dude!
@apocraphontripp4728
Dude, this is brilliant. Eres un pingu. Dude, perfect this method and sell them.
@Theverdikt
Nice video. Thank you for all information. I would like to add that the artillery sidewinder x1 has difficulties printing above 255° because the main gears becomes hot and the filament stuck into it. So, I have added a fan on the top of the extruder giving airflow on the filament gears, that gives no more issues on this part and I can print perfectly at 265°.
@MomoCoder
Lol those smooth bottles look funny :D
@sarathai2876
Your abilities are amazing.
@rhoula
Unbelievable skills. Thank you so much for sharing.
