3M makes both products you need, the 3M™ Super Strength Molding Tape and the 3M™ Adhesion Promoter 06396. The tape is available in different widths and is gray in color with a red backing strip.
You need to clean the surfaces that are to be joined with solvent, isopropyl alcohol will do the job. Then apply the adhesion promoter per the instructions, followed by applying the double sided tape to one part, removing the red liner, and then applying it to the other part. Press and hold in place (it's a pressure sensitive adhesive), I suggest at least 30 seconds. The bond will increase in strength over time, so don't load any stuff into the organizer for at least 12 hours, preferably 24 hours.
This tape is pretty tough. I used it in my saddlebag to mount a couple straps that I use to secure the tool kit. It's been there for almost ten years and still doing just fine. I also used it to secure the battery tender pigtail to the metal panel on the frame between the engine and the battery compartment. That has also been there for about ten years.
Surface prep is very important, as is the case with any adhesive. The attached pdf file is the tech sheet for the adhesion promoter and includes the instructions for its use.
