This tool builds a C-shaped clip sized around your cable and exports it as an STL. Enter the cable diameter, mouth opening and clip width in millimetres; the two-tab base comes ready to screw or tape down, and the model is computed in your browser.
The clip is open at the top: you press the cable in through the mouth, and once it is inside the mouth holds it. The mouth is always generated narrower than the cable, because an opening as wide as the cable lets it fall straight back out. The panel reports the limit it applied.
Free, no sign-up. Change the sizes in millimetres and download the STL.

The mouth is the gap at the top, and on its own it decides whether the clip works. A mouth wider than the cable holds nothing; a mouth that is far too narrow permanently splays the lips as you force the cable in. In practice around two thirds of the cable diameter works best.
The base has two tabs, each with a screw hole. A 3 mm wood screw holds well in timber and MDF, and a self-tapping screw works on metal profile. Entering 0 for the hole diameter removes the holes completely.
The loop bore is sized from the cable diameter, so the cable sits loose inside rather than clamped. The only pressure is while it passes the mouth, and that is brief enough not to mark the jacket.
One clip every 20-30 cm keeps a run tidy under a desk. Laying out a batch in one job is the practical approach, since each clip takes only 5-10 minutes.
Yes if you want a very flexible clip, but TPU squashes as a screw tightens and the base bulges. If you choose TPU, use tape instead of screws.
This tool builds the screw-on or adhesive base a cable tie passes through, sized by you and exported as an STL. Enter the base width and depth plus the slot width and length in millimetres, and the model is computed in your browser ready to download.

This tool builds a screw-on wall hook to your measurements and exports it as an STL. Pick a hook style, type the plate size and how far the hook should reach out in millimetres, set the screw holes, and the model is computed in your browser.

This page opens the DrawSTL L bracket template: a parametric right-angle corner bracket with screw holes that you size in millimetres and download as a print-ready STL. You give the horizontal arm, the vertical arm, the width and the thickness, and the holes are spaced evenly along each arm.
