I used the large IKEA Lack table (118cm x 78cm x 45cm), which provides enough space for at least two 3D printers of similar size to the Anycubic Kobra 3.
The connector, however, is compatible with any size of the Lack table.

Print Settings:

• Material: PLA
• Layer Height: 0.2mm 
• Infill: 20% 
• Wall/Perimeter Lines: 4 walls (for stability)
• Top/Bottom Layers: 4-5 layers
• Nozzle Size: 0.4mm (standard)
• Supports:  No

Let me know if you need help adjusting these settings! 

Instructions:

1. Flip the lower table upside down.
2. Place the connector between the two tables.
3. A 10cm riser is necessary to achieve a total height of 100cm. This allows the use of standard IKEA doors to construct the walls.

For the back panel and as a shelf, you can use the provided board from the large Lack table.

Materials I used for the sidewalls:

• 4x HAVSTORP 40x100cm

For the doors:

• 2x HAVSTORP 60x100cm

Additional requirements:

• Various wood screws, approximately 25mm in length.

I printed the connectors in orange, though in hindsight, white might have looked better. But ultimately, the choice of color is a matter of personal preference.
