Home and desk
This tool builds a flanged cable grommet and its cap for the cable hole in your desk and exports both parts as one STL. Choose a standard 35, 50, 60 or 80 mm hole or enter your own diameter.
The body outer diameter is the hole size minus the fit tolerance and its length equals the desk thickness, while the flange covers the hole edge. The cap seats in a 45° counterbore in the flange with the same tolerance and sits flush with it; a skirt underneath keeps it centred. A slotted cap lets cables out through an edge notch, a comb cap passes cables anywhere between thin flexible teeth, and a closed cap covers an unused hole.
Free, no sign-up. Change the sizes in millimetres and download the STL.
Each variant is the same template with different settings. Follow the link and the editor opens with those values.

Office desks mostly use 60 and 80 mm holes, smaller desks 35 and 50 mm. Drilled holes are usually slightly oversize, and holes in laminated chipboard are often uneven. The default 0.4 mm tolerance pushes in by hand in most holes.
The slotted cap has a round ended notch from the edge towards the centre where cables come out. The comb cap has a wider notch with 1.2 mm flexible teeth on top: you press cables between the teeth and dust or small items do not drop through. The closed cap only has a lift recess at the edge.
The body length equals the desk thickness, from 15 to 40 mm. On a thicker desk the body is simply shorter and not visible from below.
Yes, it turns freely in the counterbore. Turn the slot towards your cables and leave it there.
The tool goes up to 100 mm; at that size the body and cap still fit a 220 mm bed together.
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.

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 page opens the DrawSTL plug template: a parametric flanged plug for pipe ends, desk holes and tube profiles, sized in millimetres and downloaded as a print-ready STL. The plug diameter is the body that enters the hole, and the flange diameter is the visible cap that rests on the surface around it.
