I have very little living/working space of my own and so, in order to keep my personal bike in working order, I need to be able to transport "bike mechanic stuff" (e.g. tools, screws, cables, inner tubes, etc.) in an efficient, safe way to places where I can work on my bike and have access to bigger things I can't own (e.g. repair/truing stands). Additionally, I need to be able to have these assorted things well-organized and easy to move without a lot of packing/unpacking: I've had stuff stolen† from me while using communal workspaces which were busy because I either had stuff spread out so far that it wasn't quite within my "personal bubble" of control or I had to leave my space looking for something and, when I came back, something important was missing. Finally, even without the threat of theft, I nearly always lose at least one washer/screw/annoyingly-small thing when working on my bike.
Since I assume I'm not the only person in the world who has this sort of situation, are there any sort of guidelines on ways to quickly and efficiently store/transport bike repair/maintenance gear on one's person (e.g. in a backpack)?-- I haven't got a car, so I need to be able to easily carry it myself.
† I write "stolen" rather than "accidentally taken from me" after I shouted: "Hey, did anyone take a
thingamabob from this
location a few minutes ago?" and no one answered: Even if you accidentally took something, if you don't fess up, you're no better than someone who took it deliberately without intending on returning it.
