Edit: Updated the V2 base to make it easier to remove → V2.1
Installation
Attach the base with two screws. Then sling the cables around it and snap the cover in place.
Printing
I added a new version with wider clips that prints without supports.
The base prints on the side. I used PETG for this part
The Cover prints as shown below. I used PLA for this part.
The author remixed this model.
Simpler design with only two parts instead of 3. Also bigger to accommodate 2 cables.
