For example, from my first days, when I change Club Mate cardboard box to plastic one, I use box bought from Amazon, with dimensions:
43cm x 38cm x 32cm high (I would like use 36 cm, but not all shelves can accomodate more then 35 cm)
which is classified as 35 L box.
It same, as you can buy at most Stationary shops across London (one per 13 GBP, or 3 each per 9 GBP) and can vary with color and transparency level.
It really depend, what you store inside, how heavy will be. It is simply different, if you accommodate inside 4 pcs of very heavy batteries, which each can have up to 25 kg :-) (no, I believe as nobody make something like this, it is forbidden and dangerous) or you will have inside cables, and small things...
I have another, BIG box, I believe, it have 80 to 100 litres, which accommodate my storage request. And yes, this one is very heavy, due things, which are inside. It accomodate 3 in 1 or most likely LOTs in 1 projects, which I have allowed by ONE storage request.
It is little bit not really OK, probably, should be requested each project separately and in one moment have 3 different storage requests, flowing in time and make more and more mess at system, with passed deadlines, separate announcements on ML, etc etc etc.
It is my 3rd turn at this system, it always start on begin of request with some amount, which, in 1/3 grow up, and then in middle is less and less things inside, how projects go ahead. At end, I try always spare parts give away to other members, which can use them (Hi Andy T. & Patrick D. at first row :-))) which are my general recipients of spare parts. :-) but not only them :-)
It looks complicated, but:
- save storage system mess
- allow working on 3 to 4 general projects flowing at time scale, in order, which can vary time to time, depend how much spare time I have
- avoid "passed deadline" X times, it is risk for one time, but I guess, I do not have this problem in the past.
System is, as Members box I using for "daily parts", means parts and stuff, which I using obviously, when I am at space.
Sometimes move few things into "storage box" when know, as will not work on it for 2 weeks.
If know, as something take more time as I have and need to postpone or abadone project, I move stuff to commercial storage, which I use generaly for personal things.
This system allow me to be maximum flexible as I can, but also, do not make any mess downstairs, because everything is nicely inside one of this boxes, no alongside, on top, or somewhere near. Of course, this i not good idea for all people, it can be handle only for small or medium stuff, which is able accommodate into boxes.
