I have added a video explaining how I added honeycombs to the caddy.
By request, I have added the honeycomb SCAD that I use. As well as an STL.
Couldn't find any storage bins I liked. So I designed my own customizer.
I have also added an option to have "cutouts" on certain sides, so that you can add your own honeycomb patterns in those cutouts... but this SCAD does not create those honeycomb patterns, you must add them to your STLs yourself.
