A general purpose box I made for my version of the excellent Honeycomb storage wall by RostaP | Download free STL model | Printables.com 

I designed it for 2 containers of super glue but obviously it would work for whatever. In the second picture you can see that I mixed the attachment insert directly onto the back of the box so it all comes and goes as one piece rather than bolting or friction fitting into a separate base piece.
