This model is a two-part cable management tunnel designed to hide and organize thin cables, such as LED light wires installed under kitchen cabinets, bookshelves, or dressers.
It provides a clean and aesthetic way to route cables while keeping them easily accessible and tidy.

The design consists of two pieces that can be connected in two different ways:

• by sliding one piece into the other from the side, which is the easiest and most reliable method, or
• by pressing one part into the other until it snaps in place, which also works but requires more force and precision.

The tunnel can be mounted both on the bottom or top side of furniture surfaces.
Because the model is relatively small, the walls themselves act as internal structure, so the infill percentage does not matter — it prints strong enough with solid perimeters alone.

Recommended Print Settings

• Filament: PLA (recommended)
• Nozzle diameter: 0.4 mm
• Layer height: 0.2 mm
• Wall count (perimeters): 2 walls, both top and bottom
• Infill: not important (the walls are thick enough)
• Top and bottom layers: 2
• Ironing: off (not necessary)
• Supports: not required
• Adhesion (brim or raft): not needed if your bed is well-leveled
• Nozzle temperature: 200–210 °C for PLA
• Bed temperature: 55–60 °C
• Alternative material: PETG can be used, but PLA performs better for snap fitting and is less prone to cracking

Additional Notes

This is a compact, quick-to-print model, ideal for producing several sections to create a continuous cable channel.
Using PLA is recommended because the parts are not exposed to UV light, and PLA’s slight flexibility makes it easier to snap-fit one part into the other without breaking.
No surface finishing or ironing is required — the print comes out clean with standard settings.
Perfect for anyone looking to keep LED cables or other small wires hidden while maintaining a clean, professional look in furniture setups.
