This cable management clip holds cables securely in place, yet lets you easily add or remove cables when needed. It was inspired by a clip I used on the job years ago. Nobody knew who made them yet everyone wanted them, so I went ahead and recreated it using OpenSCAD.
Several ready-to-print versions are included. Large will easily hold 24+ cat6 cables. Medium is good for about 8 cat6 cables or 6 line cords. Small will hold 2 cat6 cables or several smaller wires, small/tall is good for 3 cat6 cables and for bunching extra wire from a/c adapters. OpenSCAD source is included so you can customize to your heart's content.
If you customize, I recommend the open base/two screws option since it gives the clip more flex. If you are using double-side tape, go with closed back/no screws. Don't make the sides too thick as they will be too stiff and break off.
I printed mine in black ABS at 50% infill, 0.3mm layers, base down, no support. ABS has advantages here since if you want to make your clips stronger, you can use acetone polishing to chemically weld the printed layers. To do this, get a large ziplock bag, a sheet of paper towel, and some acetone. Wad up the paper towel and dampen it with acetone, then place the wad in a corner of the bag. Place your printed parts inside the bag and seal it. After about an hour remove the parts (hold your breath) and let them air out overnight.
