Desk-Edge Cable Clamp — Clip-On with Printable Thumbscrew

A clip-on desk-edge cable clamp that routes one cable through a C-shaped

hook on the side. No metal parts, no tools — the whole thing is three

printed pieces.

Prints:

• cable_holder_body.stl— the C-frame with the threaded hole and side

•   cable hook (the blue body in the photos).

• - cable_holder_screw.stl— knurled thumbscrew with a fully printable

•   trapezoidal thread (the red knob).

• - cable_holder_pad.stl— small swivel cap that snaps onto the screw

•   tip so it doesn't bite the table underside.

Fits desk tops up to about 55 mm thick. Snap a cable into the C-hook

from the side; the inner curl keeps it from popping back out.

Print the body on its side (bore horizontal), the screw knob-down,

the pad flat. PLA or PETG, 0.2 mm layers, 3 walls, no supports. Screw

the thumbscrew up into the body until it clamps firmly against the

underside of the desk.
