Certain NavePoint enclosed server / networking racks come with a ~ 340x60mm removable panel on the top and bottom for cable management / entry. Instead of trying to cut this panel or leaving this massive hole completely open, I designed this make to manage the cables more neatly.
In PrusaSlicer, stand the model on end, use the Cut feature to cut the panel in half, and then lay the 2 pieces flat again to print on a Prusa i3 bed. Glue the pieces together once printed.
Blank 3MF included so you can remix and make your own holes / slots!
