Summary

This is a single coil pickup design for solid body 5 string banjos.

The poles are separated by 7.9 mm (on center) and the base component component has a slot to accomodate a 50 x 10 x 5 mm neodymium magnet (which is probably a terrible choice but it's the one I have at the moment).

The overall size is : 22 x 65 x 18 mm

I have not yet assembled and tested this pickup so I don't know how much wire I'll be able to put in the coil because I eyeballed it but it should be over dimensioned to accomodate a beefy 42 awg coil.

The project can also be found in OnShapes public project repository under the name "5 String banjo pickup"
