Stackable, module tray, bin, organizer - Multisize

- These trays can be stacked and moduled as you want.
- You have 2 length size options, 100 and 200 mm and 4 height options, 15, 30, 45, 60 mm.
As the height is a multiple of 15, you can stack side by side as many as you want.
- You have also 6 div options, 0, 2, 3, 4, 5 and 6 divisions.

I had some issues with fitting at first and tried to improve it. Let me know if everything is ok.

Notes Rev 1:
I put some reinforcement for some 0 and 2 divs trays, because it was opening when you stack other trays upon it.
