I bought an Alexa capable controller for my LED lights. LED's have a 4 pin connector that is easily dislodged or unplugged. This holds the wires into the controller. Controller snaps in and won't fall out. I made it using PLA. If I were to do it again, I'd use TPU for easier installation and removal of the controller. Controller link below:
