I've tried other similar cable management designs but encountered two issues:

1. The cable openings were too large (about 5.8mm) for MFI/Type C cables.
2. The cable connector (head) wiggled a lot due to the shallow pocket.

In my design, I maintained the same dimensions (approximately 10cmx2cmx1.5cm), but I narrowed the opening to 3.5mm and deepened the pocket for better stability of the cable connector.
 

The wall attached to the table is on the slim end, but I don’t see this as a problem. Still, I thought it was worth mentioning.

I’LL UPDATE THE DESIGN FILES BASED ON YOUR FEEDBACK. PLEASE LET ME KNOW IF THERE’S ANYTHING YOU’D LIKE TO SEE CHANGED OR MODIFIED.
