A cable protector for cable laid on the floor.

This was designed for flat HDMI and VGA cables laid between the gaming computer and a projector. The segments (links) allow the protector to follow a curved path. A low profile, from customizability to just fit the cables, gives additional safety. Use tape to hold the cable in place. Double sided carpet tape can be used on the floor-side to hold the protector to the floor.

Most flat cables will take a 3 mm height on a hardwood floor. The customizer defaults are for a "standard" round cable core of 13 mm (0.5"). Carpeted floor will stress the cable and protector more due to the substrate flex. You can minimize breakage of the bridge and cable by using a greater attack angle, looser fit, and a narrower, thicker bridge.

For round cables, Attack angle = 30 Channel height = 13 Channel width = 13 Wall = 2 // equivalent to bridge thickness

For flat cables, Attack angle = 12 Channel height = 3 Channel width = 20 Wall = 2 // equivalent to bridge thickness

The protector is supplied in three versions. A customizer selector, CM_link.scad, shows proper assembly in the "both" setting. The other two settings allow parts to be made singly for small bed printers. Making channels wider than the cable allows for the protector to curve.

An attack angle of <=12 degrees is recommended for those with disabilities (ADA compliant). This recommendation is relaxed for height changes of less than 12 mm outdoors. There is no specific recommendation for indoor uses. Many commercial cable protectors use attack angles of >20 degrees to achieve heights of 16 mm or more.

Customizer notes: Some settings break the model. Wide channel widths, high channel heights and low attack angles are not compatible. No bound checking is implemented.

You will notice that on low attack angles the customizer displays a very tiny object. The underlying, masked out cylinder is quite large. The printed size may also be quite large. Like an iceberg, you only get to see the upper 10%!
