I really enjoy the organization and aesthetic that the underware system provides, but the pieces don't seem to be able to hold much more than just simple cables. This lead a bunch of creators to come up with some other clever mounts for cable spools and power supply clips, but they all destroy the aesthetics and leave cables exposed. The online generator is great for custom pieces until you want something deeper than the standard cable clips and when you try to add some angle out for better hold, it generates relief cuts that actually make the hold weaker. So my solution was underware HD. I have increased the wall thickness, added a slight taper out, and made a few adjustments to the teeth to have a more significant bite.  The power supply holder also has some slots cut out for airflow. 

Plate 1 is a simple 3 unit wide by 4 unit long 35mm deep channel

Plate 2 is a 3W by 6L with a taper into a centered 1 unit wide. Constant 35mm depth

Plate 3 is a 2W by 4L that tapers into a single side. Wide portion 35mm deep and tapers up to meet a standard underware channel over 2 units. Requires supports

Plate 4 is a cable coil designed to but up next to the power supply and house extra cord. 

Plate 5 is the same as Plate 4 with the cable in notch on the opposite side

Plate 6 is a 2W by 4L 35mm deep that tapers into a single side and meets up with a standard underware channel. (same purpose as plate 3, but doesn't require support)

Plate 7 is a 4W by 8L mount for a power supply
