Design the Cable Clip

THE BASIC CLIP:

A small piece that:
  - Attaches to the desk edge (or wall).
  - Holds a cable in place.
  - Allows easy removal.

PARAMETERS:

cable_diameter = 5mm  # the cable to hold
desk_edge = 22mm      # edge thickness
clip_thickness = 3mm  # the clip's own thickness
material = "PETG"     # flexible enough to flex

CLIP DESIGN:

A C-shape that wraps around the cable.
The opening is slightly smaller than cable diameter.
Cable presses through the opening; clip springs back.

DESIGN STEPS (in Tinkercad / Fusion):

Step 1: Create the desk-edge attachment.
  A C-shape that fits over the desk edge.
  Outer dimension: desk_edge + 2*thickness.
  Inner: desk_edge + 0.5mm (clearance).

Step 2: Add cable holder.
  Extension that comes off the back of the attachment.
  C-shape with cable_diameter cavity.

  Opening at the side; cable enters from above.

Step 3: Add chamfer to edges.
  Smooth the edges where the cable enters.

  Reduces friction during installation.

  Soften visible edges.

EXAMPLE DIMENSIONS:

For a 5mm cable on a 22mm desk:
  Outer width: 22 + 6 = 28mm.
  Cable holder offset: 15mm from attachment.
  Cable cavity: 5mm diameter.
  Opening: 4mm (so cable presses in).

For multiple cables:
  Multiple holders in a row.
  Spacing: 8-10mm between cables (gives breathing room).

PRINT SETTINGS:

  Material: PETG (some flex).
  Walls: 3-4 (sturdy).
  Infill: 20% gyroid.
  Print orientation: holder side facing up.

  Time: 15-30 min per clip.

ASSEMBLY:

  Press the clip onto the desk edge.
  Press cable into the holder.

  No screws or adhesive.

WHEN IT WORKS:

  - Desk edge has consistent dimension.
  - Cable diameter is consistent.
  - Clip's flex matches cable + edge tolerances.

WHEN IT DOESN'T:

  - Cable too thick: holder too small; cable won't fit.
  - Cable too thin: holder too loose; cable slides out.
  - Desk too thin/thick: attachment doesn't grip.

ITERATION:

Print v1.
Check fit.
Adjust:
  - Tighter? Make cable holder slightly smaller (4.7mm vs 5mm).
  - Looser? Make it larger (5.3mm).

Repeat until perfect.

VARIATIONS:

ANGLED CLIP:
  Holds cable at an angle (e.g., 45° from desk surface).

MULTI-CABLE CLIP:
  Holds 2-3 cables in a row.

WALL CLIP:
  Mounts to a wall instead of desk edge.
  Different geometry: flat against wall vs wrapping around edge.

CABLE BUNDLE CLIP:
  Holds multiple cables grouped together.

PRO TIP:

Make the cable holder slightly tapered (1-2°).
The cable wedges in tighter when pulled.
But: still removable by hand.
