Coloring PET1 Plastic Bottles to make FREE Rainbow 3D Printing Filament!

Rainbow Coloring some recycled PET1 Plastic 1-gallon Water Bottles to make FREE 3D Printing Filament. In this video I'm showing the small machine I built to slowly rotate the bottles while I color the inside. This was built with an Arduino Nano and a stepper motor driver. i wrote the code myself.

Looks like you’re enjoying having the time to work on fun projects! I like the bottle turner. You think like I do, coming up with projects to make other projects easier.

Thanks! And it was a fun, practical way to learn a little more about coding on the Arduino. 😅

Wow, you have the models and will make a video demonstrating how to build this machine, I found it very interesting!!!
👏👏👏👏👏👏👏👏👏👏👏

I have the models in TinkerCAD, but I don’t think I ever recorded the electronic part numbers or did a schematic for it. Honestly, I didn’t think anyone else would be interested in it. That, and I often get questioned as to why I color the inside of the bottle instead of the outside. And yes, I have a very practical reason for it…. I color the inside, and when I feed the ribbon into the Pultruder I make sure the ribbon gets rolled into a tube with that colored portion going to the inside of the completed filament. That way the ink from the markers is INSIDE the filament, not on the outside where it could contaminate my hot-end. That way I don’t get blobs of color when I’m printing with clear filament (for example).

@@KevinGroninga3D I understand, I asked you if you have or would release the models because sometimes it helps someone (like me) who doesn't know how to model. Thanks!

[@KevinGroninga3D]

@@FrancisBentoMarques do you have an account in TinkerCAD.com? I could make that project ‘public’ so you could download the models within it.

Pls do it kevin
