I made a holder for straps and other stuff for my ATX 600 rack (60mm profile). There are a few things that could be improved, but basically it works well, so I'm using my prototype. You need 1x 6mm fusion thread + 1x M6x40mm screw as well as at least 2x M4 fusion thread and at least 2x M4x30 screw (up to 4 would be possible, but probably not necessary). The holder can be a bit loose (it is in my case). To reduce the distance, you can stick some duct tape into the holder to compensate for the distance to the rack. I printed it out of ABS. There are additional attachments in the other models.
The author marked this model as their own original creation.
