To prevent the final assembly from leaning forward when screws are tightened and load added, you can insert pieces of prime line or single layer skirt at the front in between the modules.
The rest of the needed parts you can find in the original design by @FruitieX
The author remixed this model.
Since there are 10 different colors in a typical dupoint ribbon cable I remixed the comb with 10 kerfs so you can sort your jumper leads by color.
In addition to the above 35mm spacer was added.
