NOTE: the 2 taller ones on the right in the photos were earlier prototypes that didn't work well. i just havent finished printing replacements yet (and I need to get more command strips)
In my effortys to hide everything I can inside my "entertainment center" (wall mounted Ikea Besta with doors) I came up with this slim design to hold cables on the inside of the doors. There is about a 1inch cap between the door and the shelves inside. I also wanted a clean look that was easy to remove if I wanted so i designed these to use 3m command strips. The actually container slides onto the mounting bracket and hides the command strips pull tag so you don't have to see any seems or drill any holes. If you decide you want to move/remove it juse slide off the container and pull the release tab.
This prints open end down (see photos / screen shots) and should not need any supports. There is a small notch in inside of the bottom so that one layer makes 2 small bridges and then the next layer bridges between them (please see screen shots). I print at 0.2 for speed. 20% infill should be fine. I intend to make other organizers that use this mount in the future so if anyone has any ideas please let me know.

please read the details about the bridging. I've only tested this in slic3r but cura should handle it the same way. Previewing is important or the inside could end up a bit of a mess.
