I wanted to use this cheap and effective shelf without it constantly hitting the glass wall of my shower. So I created this little modification. It's a press fit design, no glue or other tools are needed. However, keep in mind that KROKFJORDEN is not a particularly precisely made product and the dimensions of some parts may vary significantly. I've tried my best to minimize the risk of parts not fitting properly.
There are 2 parts (differences between versions are explained in the file descriptions):
I recommend using PETG (tolerances were tested for this material only) or other slightly compliant material. I just used the standard Prusament PETG profile from PrusaSlicer: 0,2 mm layer height, 2 perimeters, 20% grid infill, and no support.
Just press parts into the right places as seen in the picture above. It may require quite a lot of force but then it should snugly click into the right space.
