Open Emag Electromagnet Wrapping Machine

#Intro to Open Emag

After spending roughly 15$ USD on ingredients and printing this design (with 3$ of PLA plastic), you can own a high quality coil wrapping machine that would have costed many times more in the proprietary world. We all deserve good electromagnets. My reward (eventually) will be to see the photos of other people's successful renditions.

WARNING: This project is JUST THE MECHANICAL apparatus. I do not supply code for controlling the device because there's too many ways to do it. I discuss many options for controlling the servo and motor, but I do not hold your hand and walk you through to finishing the project. Most people reading this are interested in doing something really nerdy and specific, so this modular approach is likely a feature, not a flaw.


This is an OpenScad project that uses a central file (openEmag.scad) that calls upon all of the other files to accumulate a ready-to-print kit that can be assembled (along with a few products) into an electro
