DIY Arduino Based Bobbin Winding Machine

Hello makers in this post about DIY automatic Arduino based bobbin winding machine.

Bobbins are the small metal spools used in sewing machine, bobbins are filled with thread to stich cloths. This bobbins are frequently getting empty and you need to rewind it with thread again and again. So I made this machine it can automatically wind thread to maximum 12 bobbins in single run. there are already many bobbin winding machines are available in market. But there prices are more than 500$ but my this DIY arduino based bobbin winding machine can build under 100$.

JLCPB is best PCB manufacturer they have very resonable PCB pricing and fast PCB production

You can surely consider JLPCB for your any PCB needs

CAD File

Major components of this machine is made up from 6MM white acrylic sheet which I have cut in my CNC router machine.

I have made available all components here in DXF format you can easily load it to any CAD/CAM software to modify or make the part as I made.
