These models print FAST and use less filament because they are designed to be printed in Spiral Vase Mode (aka Spiralize Outer Contour).  Mix and Match 6 drawer sizes. Drawer dividers allow you to divide a drawer in half or thirds. For heavy objects use the braces shown in the pictures to support the sides near the front of the drawers. I've been able to load it up with bolts, nails, screws, and batteries and the drawers still operate smoothly. 

Inner dimensions of drawers,  width (mm) x height (mm) x depth (mm):

6x4: 87 x 55 x 146 

6x3: 87 x 38 x 146 

6x2: 87 x 23 x 146 

4x4: 55 x 55 x 146 

4x3: 55 x 38 x 146 

4x2: 55 x 23 x 146 

This has been tested with Cura 4.4 and Slic3r 1.3. Since the tolerances depend on the thickness of the walls generated by the slicer I recommend printing with a 0.4mm nozzle and 0.4mm line width in your slicer settings. The drawers and enclosures need to be printed in Spiralize Vase mode, the braces and dividers print normally with infill. 

Before purchasing this model you can test the fit by printing the free model: Mini Modular Small Parts Drawers. These drawers can interlock above or below the Vase Mode Hexagonal Modular Drawers.
