I modified my design to hold mini-LED Holiday Lights on ½ inch PCV around my windows.
Original Design was "1/2" PVC Perpendicular PPC (Pixel Pipe Clip) for 12mm Bullet Pixels" on other design repository: https://www.thingiverse.com/thing:5218331 by https://www.thingiverse.com/PHOENlX
The author remixed this model.
