Cleanly route cables behind your Kallax. You'll need support for this print unless you find a way to split it elegantly. Keep in mind that those cable routing pins are not too rigid when they are printed perpendicular to the layer lines. If you are routing thick power cables and don't want them to break off immediately, print it on its side. I would recommend a tougher material than PLA.
