Wire Clamp for Model Railroads

thingiverse

This clamp gives you the power to securely grasp a pair of bus wires against the underside of your layout. You can personalise several key settings, such as the dimensions of the clamps and how many are printed simultaneously. I've uploaded an STL file too, which might be all you need to go with. You're free to use Customizer or load the .SCAD file directly into OpenScad if that's what you prefer.
