Tired of having cables everywhere? Just print a cable manager that regroups all of them.

Materials: PLA / PETG / TPU

Default inner diameter (ID): 12 mm

Default height: 85 mm

Supports: not required at default size or scaled uniformly 

Orientation: print upright
Print time: 45 min (for default size)

Filament required: 3g (for default size)

How to scale

A) Change the inner diameter (and keep proportions)

Scale uniformly on all axes (X=Y=Z).

• Scale % for diameter = (Desired ID in mm ÷ 12) × 100
• Example: Desired ID = 15 mm → (15/12)×100 = 125 % (uniform)

Uniform scaling changes everything (diameter and height) but preserves geometry and overhang angles.

B) Change only the height (and keep proportions)

Scale Z-axis only (X=Y=100 %, Z = value below).

• Scale % for height (Z only) = (Desired Height in mm ÷ 85) × 100
• Example: Desired height = 100 mm → (100/85)×100 ≈ 118 % (Z only)

Do not combine A and B on the same print: either scale uniformly for diameter changes or scale Z only for height changes. Doing both can distort features and hurt printability.

Tips

• Round scale factors to the nearest 0.5–1 % if your slicer snaps values.
• For snug cable fits, allow +0.2–0.5 mm clearance (more if printing in flexible TPU).
• Typical settings: 0.2 mm layer height, 2–3 perimeters, 15–25 % infill.
• Height could generate print fails or bad prints because of the vibrations of the bed (A1, A1mini) otherwise on corex-y machines shouldn't (P1S,X1C,H2D)
• PETG and TPU are more suitable for this application, but PLA will also get the job done.

Quick reference

• ID 14 mm → 117 % uniform
• ID 20 mm → 167 % uniform
• Height 70 mm → 82 % Z only
• Height 120 mm → 141 % Z only

Warning: If you non-uniformly scale X/Y to alter diameter without matching Z (i.e., not using option A), you may change overhang angles and lose self-supporting geometry—prints can fail. Stick to A or B, not both. 

Warning: The increased height of the standard model may cause print failures or poor quality on bed-slinging machines (A1, A1 Mini) due to vibrations of the part. On CoreXY machines (P1S, X1C, H2D), this issue should not occur.
