Customizable Modular Cable Floor Runner/Cover

A customizable dome-shaped cable floor runner designed to protect and organize cables running across floors. Features a smooth, low-profile dome that's comfortable to walk over and won't catch on shoes or wheels.

Key Features:

• Dome profile with bezier spline control - Smooth, customizable curve that starts slightly concave at the base for a natural transition to the floor
• Oval cable channel - Sized to fit your specific cables
• Interlocking dovetail connectors - Connect multiple segments together for any length run
• Curved sections available - Create turns and bends in your cable path
• Fully parametric - Adjust all dimensions to fit your needs

Customization Options

Dome Shape Control:The dome_curve_points array lets you fine-tune the cross-section profile:

dome_curve_points = [

    [1.0, 0],      // Base

    [0.75, 0.1],   // Concave control

    [0.7, 0.25],   // Inflection point

    [0.3, 0.75],   // Convex control

    [0.15, 1]      // Near peak

Print Settings

Recommended:

• Layer height: 0.2mm
• Infill: 15-20% (gyroid or grid)
• Walls: 3 perimeters
• Supports: None needed when printed dome-side up
• Material: PLA, PETG, or ASA for outdoor use

Orientation: Print with the flat base on the build plate (dome facing up)

Assembly

1. Print segments - Print as many straight and curved pieces as needed
2. Connect pieces - Slide the male dovetail of one piece into the female slot of the next.  A bit of superglue can be used if the configuration will be permanent.
3. Route cables - Lay cables in the channel before connecting the last piece
4. Secure ends - Print end caps by setting enable_front_dovetail = false or enable_back_dovetail = false

Creating Curved Runs

Set curve_angle to create curved sections:

• Positive values (e.g., 30) = curves right
• Negative values (e.g., -30) = curves left
• The curve radius is automatically calculated to maintain the segment length

Example: For a 90° turn, print three pieces with curve_angle = 30

Tips

• For heavy foot traffic areas, increase dome_height for added strength
• Use channel_floor_thickness = 0 for an open bottom (easier cable insertion)
• The dovetail clearance (dovetail_clearance = 0.15) may need adjustment for your printer
• For outdoor use, print in ASA or PETG
• For indoor use, print in TPU for comfort when stepping on it
