About this design

The Under-Desk Drawer is a hidden drawer that screws under your desk top. Handy for pens, chargers, keys or small items you want within reach without cluttering the desk.

The inside is exactly 3 × 3 Gridfinity units (126.5 × 126.5 mm) and 48 mm tall, so bins up to 6 units with stacking lip fit, for example from the Gridfinity Starter Kit. An optional 3x3 baseplate is included. The drawer is compatible with Gridfinity; the standard is covered by the MIT license.

  • Drawer outside: 131.3 × 133.4 × 50 mm, inside 126.5 × 126.5 × 48 mm
  • Width with rails 145.9 mm, height under the desk 69.5 mm
  • 137.4 mm dovetail rails with 0.3 mm clearance, gentle click when closed
  • Separate front with finger pull, drill guide and optional baseplate
  • No supports, digitally checked for printability

Print tips: 0.2 mm layers, 4 walls, 25% infill, preferably PETG for the rails. Print the drawer upright, the rails with the flat desk side on the bed, the front upright on its bottom edge and the drill guide flat (twice).

Mounting: slide both rails into the two drill guides, hold everything against the desk top and fix the rails with 6 countersunk 4 mm screws. Pick screws at least 5 mm shorter than your desk top plus the 5 mm rail plate. Then slide the front onto the drawer and the drawer into the rails.

You get six STL files and one 3MF.

Designer's tip

Print the drawer upright, the rails with the flat desk side on the bed, the front upright on its bottom edge and the drill guide flat (print it twice). Use at least 4 walls for the rails, preferably PETG. Mounting: slide both rails into the two drill guides (front and back), hold everything against the desk top and fix the rails with 6 countersunk 4 mm screws. Pick a screw length at least 5 mm shorter than your desk top plus the 5 mm rail plate. Then slide the front onto the drawer from above and the drawer into the rails.

Frequently asked questions

Which screws do I need?

Six countersunk 4 mm screws. Choose a length at least 5 mm shorter than your desk top thickness plus the 5 mm rail plate, so the screw does not come through the top.

Do Gridfinity bins fit in the drawer?

Yes. The inside is 3 × 3 Gridfinity units and 48 mm tall, so bins up to 6 units with stacking lip fit. An optional 3x3 baseplate is included.

How do I make the drawer slide smoothly?

Use the included drill guide so the rails end up exactly parallel. The dovetail has 0.3 mm clearance per side; PETG usually slides a little more smoothly than PLA.

How much space do I need under my desk?

The drawer with rails is 145.9 mm wide and hangs 69.5 mm below the desk top. Make sure no crossbar or frame is in the way.
