Gridfinity wire spool holder

Its a wire spool holder that works with Gridfinity, its uses 2x4 grids.It has a bit of storage for screws, nut, bolts, small wires, pens etc.The spools should be about 18-19mm wide and a diameter of about 60mm, the inner diameter should be 9mm or more, so it fits the shaft.I have used these spools made by Jay, they work amazing, with this, but you can use any spool that are within the requirements. List of the requirements:OD: about 60mmID: 9mm, larger will also work, but smaller may not.Width:
