Gridfinity Underdesk Drawer Round 6x5 for Office Desk

This design gives you a compact 5 X 6 Gridfinity layout as a low profile drawer meant to be mounted under desks or shelves.

Materials/Parts:

Since the design is relatively large, I have cut the model to allow printing in parts. To assemble you need the following pieces:

1 x Frame Left

1 x Frame Right

1 x Frame Back

2 x Frame Bar (Frame Bar and Frame Bar front are identical)

1 x Drawer Front

1 x Drawer Back

(optional) 4 x Mounting Screws ( I used 1/2 inch #6 wood screws with a chamfered head)

(optional) 2 x Drawer Stop Screws (M3/M4 screw and heated inserts or M5 with no insert)

The pieces have relatively wide tolerance dovetails meant for high viscosity glue (gorilla glue or gel glues). If you have a large enough printer, you can probably just re export the design files into just one drawer piece and one frame piece. This was all cut to fit on a Core One

If you want to use double sided mounting tape to attach the drawer, and/or do not need the drawer stop, you do not need screws for this build.

Assembly Notes:

I highly recommend using masking tape to hold things together while gluing. In my build, I laid the parts out and taped them down to a cutting mat to hold things while I applied glue and let them dry. This also helps guarantee flush alignment of the bar parts so that they line up nicely for assembly.

Start by laying out all the frame pieces and getting a sense of how things go together. You will do all the gluing for the frame upside down since its easier to hold in place. In this image, the frame is upside down compared to how it would be installed.

Then put pieces of masking tape over the outward facing side of the dovetails on the left and right frame sides. This tape will be underneath during gluing.

Then tape one side down onto your work surface. This could be directly to the table, but to protect against glue I recommend using a mat or some sheets of paper.

Tape down the other side and check the distances with all three bars as you go.

Then apply glue to the dovetails and slot things together. Its easiest to do the back bar first, then the two middle ones. After seating things, you may want to go back and apply more glue.

Once the frame is assembled, lay out the drawer with the dovetails like in the image. These ones slide sideways.

Once you are comfortable with the layout, apply glue to the dovetails and the length of the gridfinity bar that is cut in half. Slide them together and hold them in place with tape.

Once dry, you can experiment with the series of holes on the front of the frame to see how far forward you are willing to let the drawer slide. Add a screw or heat insert thread to the pair of holes you like most to stop the drawer from coming out. For now, make sure you can remove the screw since you need to take the drawer out during mounting.

Mounting instructions:

Remove the drawer from the frame for now.

Tape or use clamps to temporarily position the frame on the bottom of the desk so you can mark.

Carefully mark the screw holes on the table by looking for the four holes on the outermost corners of the frame and mark the table with a pencil. These are the only chamfered holes on the design.

Drill pilot holes to match your screws at the four marked locations.

Install the screws to hold up the frame. There are large holes below each of the mounting holes to allow you to use a long screwdriver for final install.

If you want a drawer stop, re-install the drawer and add a screw to the hole you identified earlier. Leave the head hanging out so that it catches the back of the drawer when pulled out.
