Modular Wall-Mounted Drawer Organizer for 3D Printing Supplies

Model description

This is a modular drawer organizer designed mainly for small accessories and consumables used around 3D printers.

I made it because small things like nozzles, needles, screws, silicone parts, glue sticks, tools, and leftover pieces always seemed to end up scattered around the workshop. This system keeps them sorted, visible, and easy to access.

The system is built around simple wall-mounted racks. The racks are available in 2-slot, 3-slot, and 4-slot versions, and they can be mounted either horizontally or vertically depending on the available space.

The drawers are available in several sizes:

• 1-slot drawer

• 2-slot drawer

• 3-slot drawer

• 4-slot drawer

• 2-slot vertical drawer

The 1-slot drawers can be used in both horizontal and vertical rack orientation, which makes the system more flexible.

Each drawer has a front finger cutout, so it is easy to grab and pull out. The front also includes a simple holder for a custom label.

The first drawer size was designed with the dimensions of a Prusa Nozzle in its original box in mind, so it works well for storing nozzles and similar small 3D printing accessories.

Basic dimensions

Internal dimensions of a single 1-slot drawer:

61.8 × 60.2 × 85 mm (H × W × D)

Maximum rack widths:

• 2-slot rack: 135.6 mm

• 3-slot rack: 201 mm

• 4-slot rack: 266.4 mm

Please note that the 4-slot rack is too large for smaller printers such as Prusa MINI or MK3/MK4, but the 2-slot and 3-slot versions are available for smaller print beds.

The racks include 5.5 mm mounting holes behind the drawers. These holes are intended for screws with a flat head.

Print instructions

The whole system was printed in PLA, which works well enough for this type of organizer.

All racks and drawers are designed for a 0.4 mm nozzle and 3 perimeters — except for the labels, which are described separately below.

This is important because the main walls are designed as 2.4 mm thick, so they print cleanly as solid walls with 3 perimeters from each side. If you use only 2 perimeters, the slicer may generate infill inside the walls instead.

Most of my parts were printed with a 0.2 mm layer height, but I also printed several parts at 0.25 mm layer height, and both worked well.

Recommended settings:

• Material: PLA

• Nozzle: 0.4 mm

• Layer height: 0.2 mm or 0.25 mm

• Perimeters: 3

• Infill: standard/default is fine

• Supports: not needed

• Brim: not needed

The racks should be printed bottom side down.

I have not tested 0.6 mm nozzles or larger. If you try a larger nozzle and the drawer feels tight or rubs when sliding into the rack, lightly deburring the drawer corners with a deburring tool usually helps.

Labels

For the label to fit properly, it should be 55 × 20 mm.

The minimum thickness is 0.4 mm, but I recommend 0.6 mm, because thinner labels may fall out more easily.

There are three ways to make your own labels:

Old-school paper label

Use thick paper or cardstock, ideally at least 300 g/m². Business cards are often close to this thickness.

Cut out a 55 × 20 mm rectangle and write on it with a pen or pencil. Simple, fast, and works surprisingly well.

Use the blank label model

A blank label model is included in the print files.

You can add your own text to it directly in PrusaSlicer, as described from step 3 below.

Create your own label in PrusaSlicer

1. Start with an empty build plate. Right-click on the build plate, select Add Shape, and choose Box. 

   

2. In the lower-right Object manipulation panel, unlock the size lock so each dimension can be changed separately. Set the size to:

   • X = 55 mm

   • Y = 20 mm

   • Z = 0.6 mm

     

   Tip: If you plan to change and move the labels often, you can use Z = 0.4 mm instead. Just keep in mind that thinner labels may occasionally fall out when handling the drawer.

3. Right-click the label and select Add Modifier → Text.

   

4. In the Emboss settings, set Operation to Join. I also recommend changing Depth from 1 mm to around 0.4 mm, which gives you two printed layers for the text.

   

5. If you want a two-line label, open Advanced and reduce the Line gap value, so the lines are closer together.

   

That’s it.

You can of course experiment with fonts, text size, number of perimeters, and other settings. I usually use 1 perimeter for the labels.

Just remember to keep 2.5 mm of free space on both the left and right side of the label, because this is where the drawer holds the label in place. This means the maximum recommended text width is about 50 mm.

If you are printing a two-color label, do not forget to set a filament color change from the 4th layer, assuming you are using the included blank label or your own 0.6 mm thick label.

0.6 mm thick labels hold well, but they cannot be inserted into the drawer from the top. Insert one side first, bend the label slightly, and then slide in the other side. PLA can handle it. ;-)

Whether the print turned out great or not, I would be happy to see your result — feel free to share feedback or post an Add make. If you would like to modify or improve the model, I have also included the original Fusion 360 project and an exported STEP file.
