This is a remix of LM2596 with Display Case to add some rails to slide into 2020 aluminum extrusion without tools. NOTE: You really need a well tuned printer as this fits the 2020 extrusion profile exactly. If not, you will probably need to sand the rails a little to fit as desired. This uses the same lid as the parent model, so pull it from there if you want the lid.
