Since a long time, I have wanted to have a good shelf for all my Bosch tools, which are mostly stored in an L-BOXX. The L-BOXX is nice for transport, but if you stack them on top of each other, you can, of course, only open the top box. What I wanted to have is a shelf that you can move around and that has a drawer for each box to make them easily accessible. The creator, "TheMakerShedNZ," has designed a clamp for the L-BOXX that will hold them in place. To ensure that only one drawer can be open at the same time, I found a system from the manufacturer HÄFELE that is quite cheap (9.60€) for four drawers. Additionally, you only need a sheet of metal if you don't want to buy it from HÄFELE. You can also install a lock for extra "safety." (At least some will have to use force to open the boxes then.)
I will add a PDF in the next few weeks with more information, such as a parts list and where to buy. But first, I have to build everything now after planning to check what could still be missing.
