The first ones I made kind of sucked. These are designed to use some 2 sided tape and some of those velcro cable management strips. On the P1S these print with perfect tolerances that the clip piece will snap into the base. Made it two pieces so that when first setting up, you can attach the wires to the clip before attaching it to the base, which should make it a bit easier. Once their in, you will definitely have to use something to pry them out, but they can be removed and reinserted.
