Generic Customizable Spool Holder

I wanted something I could put all sorts of wires or solder spools on but couldn't find anything satisfactory/large enough/customizable on here so I designed this. By default it's 150mm tall, 120mm wide, 20mm deep at the base and 7mm at the top, has 4mm thick walls and takes 8mm rods. All of it can be customized with the customizer app (or you can modify the SCAD file yourself).
