How do I design a custom cable?

Below are some helpful instructions for each of the cable options when ordering:

Host Connector

The connector that will plug into your computer.
Most common: USB-A.

Device Connector

The connector that will plug into your keyboard's USB port.
Most common: USB-C. (Some older keyboards use Mini or Micro USB).


The finished length of your cable, after any coils and connectors are in place.

Example: Choosing a 4' USB-A to USB-C (non-detachable) cable with 6" of coils will result in the following cable:

  • [USB-C]--3"--/////6" coils/////-------3' 3"-------[USB-A]

Note: A detachable cable will feature an aviator connector immediately after the coils (to the right of the coils in the above visualization).

Cord Color

Your cable will be sleeved in colored paracord of your choice. View available cord colors.


Add additional durability and style to your cable by adding double sleeving. We use high-quality Techflex® PET expandable braided sleeving in a variety of colors. View available double-sleeving colors.

Pricing for double-sleeving is based on uncoiled cable length. It takes about 1' of cable to wrap an inch of coils. (ie: 6" coils = approx. 6' of precoiled cable)

Heatshrink Color

Heatshrink is the colored material that wraps tighly around the connectors, securing them to the cable and adding a level of support against bending and tweaking. View available heatshrink colors.

Inner diameter: 3/8"
Outer diameter: approx. 3/4"

Keyboard Port Position

Sitting at your keyboard to type -- which side of the case is the USB port nearest?

Common examples:

  • Ducky One 2 Mini: Left
  • RAMA M60-A: Center
  • KBDFans KBD8X MKII: Right
  • Drop ALT: Both (choose your preferred port)

How long can my cable be?

The commonly accepted maximum length for USB 2.0 rated cable is 15 ft. However, due to the wide variety of keyboards, we generally recommended to keep the total pre-coiled length under 12 feet. Longer cables can potentially have issues transmitting power to your device. If you use a keyboard that draws an above-average amount of power (including, but not limited to those listed below) you should do your own research regarding your keyboard's power requirements before ordering. As stated in our terms, we cannot accept returns for a cable that is not compatible with your device.

Below is a few keyboards that are notoriously sensitive to lengthy custom cables. If you plan to use a custom cable with a keyboard featuring a large amount of LEDs or electronics such as those listed below, you may consider designing a shorter cable or omitting coils:

  • Massdrop ALT, CTRL, SHFT, etc.
  • HHKB
  • Input Club's K-Type

When deciding on your finished cable's length, be sure to consider the pre-coiled cable length. That is, the length of cable prior to the coils being wrapped. On average, it takes roughly 1 foot of cable for every inch of coils.

Example: A cable with 6" of coils and a total finished length of 4' = 10' of pre-coiled cable.

What countries do you ship cables to?

We ship internationally to all countries! You will be responsible for any duties, customs, or import taxes and fees assess by your country.

What materials are used to create the cables?


We use high-quality USB 2.0 rated wire. The cable is made up of four conductors: two 28 AWG power conductors plus a pair of 28 AWG twisted data lines. These wires are protected by a braid, foil, and drain-wire shield -- all encased in a robust yet flexible PVC jacket. The double shielding provides maximum protection against data corrupting EMI/RFI.


At Noble Cables, we source only the highest grade, US-made, Type III 550 paracord. This is the commercial version of Mil Spec 550 paracord. This Nylon 550 cord is smooth and pliable which makes it nice to handle. The high 550 lb. tensile strength gives it superior strength and durability. It resists rot, mold, mildew and UV damage -- This ensures the colors will not bleed and prevents dicoloring and fading over time. With over 300 color options, there's something to match any keyboard or keycap set out there: View Paracord Colors


Double sleeving (Techflex) or PET (Polyethetlene Terephthalate) braided sleeving is a second layer of material that covers the paracord, adding an extra layer of rigity and durability. Pair any of our double-sleeving color options with your paracord of choice to create some beautiful combinations.


Heatshrink is the plastic tubing that is wrapped around the connectors, securing them to the ends of the cable. We use heatshrink with 3:1 shrink ratio, meaning that after placing it where it needs to be, heat is applied causing it to contract to a third of its original size. This holds the cable snugly to the connector's base, giving the cable's ends durability and resistant to a lifetime of bending and tweaking. Many people choose a colored heatshrink as an accent, complementing their cable's overall color theme.


These are the ends that plug into you device and computer. Be sure to check which connectors you need for your specific setup. We've listed the common USB types we offer in a question below.

What connectors do I need?

When creating a custom cable, you'll want to choose the correct connectors for your device/keyboard and computer. Below are some common USB connectors:


USB Type-A connectors typically plug into the back or front panels of your computer (or outlet adapter).


USB Type-C connectors are reversible connectors that are popular on many newer mechanical keyboards, smart phones and computers.

Mini USB

Mini-USB is a popular connector type that plugs into many mechanical keyboards, digital cameras, external hard drives, and USB hubs.

Micro USB

Micro-USB is a popular connector type that plugs into small devices like cellphones, tablets, and other portable devices.


USB Type-B connectors are square shaped, and are found on printers, scanners, and other peripheral devices.
