I turned plastic bottles into a working CNC machine that can mill real PCBs!
This DIY Mini PCB Factory is built from PET filament (made from recycled bottles) and MDF sheets.
It runs on GRBL and is fully 3D printed and CNC cut – and YES, all design files are FREE on Thingiverse!

📌 About the Project:
- Recycled PET filament from bottles
- MDF frame CNC cut
- GRBL firmware for precise PCB milling
- Perfect for makers, hobbyists, and DIY electronics
