A drawer rack whose drawers actually slide

What the mode actually builds

The rack is a frame with a single stack of drawers. You set how wide it is, how many drawers it holds, how deep they are and how tall each one is. The frame and the drawers come from the same dimensions, so they fit each other rather than being modelled separately and hoped into place.

The default starts at width 2, three drawers, depth 2 and height 3 units. That is a sensible starting point for a desk or a bench, not a size you have to accept.

Why height is set in modular units

One unit is 7 mm. A height of 3U comes out at about 21 mm, the standard for small parts such as screws, washers and connectors. At 6U a drawer takes longer tools. Working in units rather than arbitrary millimetres keeps every organizer part compatible: a drawer printed today fits a frame printed last month.

The wall: between cracked and wasted

The hint beside wall thickness states the numbers plainly. Below 1.0 mm walls crack on FDM. Above 2.5 mm filament is spent without benefit. Small parts usually need 1.2 mm, heavy tools 1.6 to 2.0 mm. A drawer full of steel screws carries more than it looks, so the choice follows the contents, not the look of the model.

The floor fails first

Below 0.8 mm the floor leaks and tears when it comes off the build plate. The common value is 1.2 mm, usually three layers with a 0.4 mm nozzle. The floor takes the weight of the contents on every pull, which is why saving material there is the most expensive saving.

Clearance decides whether a drawer moves

Below 0.3 mm parts jam, above 0.7 mm they wobble. The typical FDM value is 0.4 to 0.5 mm. Printed parts carry the tolerance of the machine that made them, so clearance is not decoration; it is the difference between a drawer and a box that will not come out.

Labels are read from a distance

Letters below 6 mm are hard to read from a metre, and above 14 mm they do not fit a standard compartment; 8 to 10 mm is typical. Label depth below 0.4 mm is invisible, above 1.0 mm it pierces a thin wall, and 0.6 mm, two layers at 0.3 mm, is typical.

The print check comes from the shared rules

The geometry is checked against the same FDM design rules the other tools use: a 0.8 mm minimum wall for two perimeters at a 0.4 mm nozzle, overhangs up to 45 degrees from vertical and bridges up to 10 mm safely. Each note carries the id of the rule behind it, not just a warning.

One codebase, three tools

Drawers and Honeycomb Wall are two modes of AM Organizer. The code and geometry are shared; only the view the app starts in is different. Parts from one mode are built by exactly the same rules as parts from the other.
