This is a kit for creating your own round cable holder for 1 screw, or for the absence of a screw (for example, glue or double-sided tape). Due to the thoughtful hole - you can insert the cable and the holder will cover itself.

The top hole will help you tighten the screw. stl files are offered simply as examples of solutions. See scad file.

This model must be oriented relative to the table, as shown in the photo, so as not to lose elasticity. There are 3 adjustable parameters (screw width, cable width and wall thickness)

Module with cone in the file name has a tapered screw cutout (for a screw with a cap not at a right angle)

If you want no screw - set 0 to screw hole size.
