Wire End Clamp for Model Railroads

The end clamp is used to clamp bus wires to each end of a baseboard. Grooves in the clamp keep the wires apart. Use OpenScad to specify the width and depth of the grooves, as well as how far apart they are.
You should be able to use Customizer to specify the parameters for this thing. You can also open the .scad file in OpenScad and adjust the parameters there and create the stl.

Or just use the stl i have also uploaded.
