Gridfinity 2x2 solder holder (wide)

This is a model based on https://makerworld.com/en/models/49316-gridfinity-solder-holder-station-1x2-format However, it is a 2x2 grid, and designed for spools up to 75mm wide.I also created a custom axle that has a built-in spring to ensure a snug fit. This is customizable, but the default axle is designed for a 19mm inner diameter spool. Because the walls are only 3.3mm wide, and larger spools can be heavy, I recommend printing with extra walls (I used 4 walls).I recommend printing the axles with gyroid infill as well.
