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

Parameter	Description	Default
runner_length	Length of each segment	160mm
runner_width	Total width of the dome base	80mm
dome_height	Height at the peak	20mm
channel_width	Width of cable channel (oval)	30mm
channel_height	Height of cable channel (oval)	15mm
curve_angle	Angle for curved pieces (0=straight)	0°
dovetail_width	Width of connector	40mm
dovetail_slide	Length of dovetail tab	12mm

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

Print segments - Print as many straight and curved pieces as needed
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.
Route cables - Lay cables in the channel before connecting the last piece
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
