Sizes: base 65 mm (length) x 22 mm (width) x 18 mm (height); mounting holes distance 49 mm. Bobbin measures 39 mm (l) x 9 mm (w) x 11 mm (h). Designed for three strings, ideal for a cigar-box-guitar setup with string distances ranging from 11-12 mm. Five millimeter iron poles require an alnico magnet, preferably 10x40 mm in size, glued underneath or using magnetized iron rods. Approximately 4500 turns of copper wire (0.42) can fit within the available space, resulting in a resistance of around 4 kOhms and producing a hot-wired sound reminiscent of a screaming Fender style guitar. Small holes on the base allow for welding copper wires to inlets and securing connecting wires. It is recommended to fix the wire spool with tape and wax potting; however, test compatibility first between the melting point of the wax and your 3D printer's plastic material. Happy crafting!
