As kbob said
These joiners let one IKEA LACK table sit on top of another securely. The cross-shaped peg makes a solid connection and ensures that the table legs won't rotate. The tables are not fastened together; you can lift the top one off at any time, and the leg part sits flat on the floor.
My twist
I liked the original design by kbob where the screws are hidden away. I wanted to use this design to place a table on top of my 3D printer. Unfortunately, the original height (20mm) was not enough to make it fit. I then adjusted the design to add a total of 100mm in height.
I split the total height into two parts of 50mm, because I think that looks better. This makes the legs modular, and you could also stack the table tops on top of each other (although I don't know why, but still). Because of the height, it was also necessary to adjust the screw holes, so that longer (and therefore thicker) screws fit in. The cross-shaped peg should be compatible with the original file.
Since the original model was called v9 somewhere, I made it v9.1 for my model. Most of the changes are minor and the parts should be compatible with each other.
Print Settings
I printed it in PLA with a layer height of 0.20mm and 10% or 20% gyroid infill. STL files are available for all parts, together with the Autodesk Fusion file, and a 3MF file with upper and lower part combined.
kbob used PETG with default settings and a coarse layer height, wich are fine for his original model.
Assembly
Print each of the upper and lower pieces four times if you want to extend the legs one side.
Print each of the upper and lower pieces eight times if you want to extend the legs on both sides.
Print the drill guides for the table and legs only once.
You will also need 8 wood screws per set (= one upper and one lower part). If you want to use the same setup as I did, you will need a total of 64 screws. Use the following table to choose the screw you want.
| Metric size | Imperial size | Comment |
|---|---|---|
| 4 x 40 | 8 x 1 1/2 | Only for lower part |
| 4 x 50 | 8 x 2 | Only for lower part |
| 5 x 60 | 10 x 2 1/2 | |
| 5 x 70 | 10 x 2 3/4 | Recommended for all parts |
Use the small holes drill guides to mark where you need to drill holes in the table and in the end of each leg. You don't need to drill the large center hole. Then drill holes, screw the parts in place, and assemble the tables.
