Step 1
- Download Helmholtz.scad from https://github.com/jetty840/HelmholtzCoil
- Change desired settings in the file, and save the resulting .stl's
- 3D Print the parts
- If splitting coils for printing, glue halves flat and let dry
- Wrap 2 coils in the SAME direction, by entering in one hole at the bottom and exiting the other, leave enough wire to connect the 2 coils together and connect to the banana plugs
- Attach banana plugs
- Orientate the coils so the windings go in the same direction and mount on the base, the inner 2 wires connect together and the outer 2 go to each of the negative/positive banana plugs
- Verify dimensions of the coils and distance. 3D printed plastic can shrink when cooled, and printer accuracy varies. If there's any substantial difference, plug the new dimensions into Helmholtz.scad
- Print the coil data from the OpenScad console, and attach to the coil base
