Simple, practical and expandable drawer system mounted under your desk.

No complicated mechanisms, no overengineering – just a clean rail + drawer design that works.

Start with a few drawers and expand as wide as your table allows.
Perfect for screws, bits, drill bits, taps or small accessories.

Dimensions

• Drawer length: 200 mm
• Drawer width: 50 mm

You can also use the drawer without any inserts.

Printing

• No supports required

⚠️ Small hack

To keep it support-free, the mounting holes have a thin top layer.
After printing, just poke it through.

Assembly

• Drawer knob is fixed using a 4 mm screw
• No special hardware needed

Notes

This is designed as a real workshop solution, not just a display model.

If you need more space → add more rails
If you need different storage → adjust  the drawer, or let me know :-)
