I have some T-Stak IV drawe. The compartments are too big for the small nuts and bolts I want to store. So I made these dividing boxes. This is for middle and back rows. These are stackable. I have also made stackable (ish) boxes for the front row. These are saved to Thingivee separately so look at my other desig for them. You have a choice of a single compartment box or a two compartment box. Two boxes (either ones) fill a compartment in the drawe. The model wont import in the correct orientation to your slicer (lazy on my part). So you will have to orientate with the base of the box on the machine table. Just as a warning if you upend your drawe all the stuff will still fall out as there is nothing in the moulding above to hold stuff in place.
