Because the cables from my Prusa to the PSU are a little to short, I was unable to use the Corner Part with the Cable duct as intended (By default it is positioned to the outside border of the Ikea Lack table).

For my setup, I came up with a solution, that simply inverts the position of the cable duct. The part that is attached to the “floor” can just be rotated 180 degrees and need no reprint.

The top part that is attached to the lid can not be rotated, because the guides for the plexi walls are not rotatable. So I simply created a new part, where the duct is moved/inverted to the inside of the enclosure, to match with the rotated floor part.

The printing is not different to the original part. It should be printable without any supports. I added some below the plexi guides,, but they are not necessary.

I dont know why, but the original step file is modified was also inverted diagonaly. Because of that I ended up with a corner part where the cable duct was in the wrong direction. For me it was no problem to rearange the cables and I decided to use that part and not print a new one. I uploaded both the “correct” and the "wrong" file here.
