This is a slim LED holder for WS2811 12mm COB LED strips which snap into 2020 extrusions for a low-profile mounting solution.
Print settings:
Scale in the X direction to whatever size you require, limited only to your Z range or bravery! I had good luck printing 175mm tall holders without issue.
Thanks to @TheKwijibo_238530 for the original inspiration and nicely designed 2020 clip, and DryFry's model 4139774 that inspired them! https://www.printables.com/model/158263-low-profile-led-strip-diffuser-2020-extrusion
