Remix for this model:
You can use this piece to add an articulating system to your ender 3 s1 pro, I personally use it for mounting an articulating arm with a camera on top.
A filet for the holes so it's easier to print, video also shows where to paint a proper support for this model.
Also go to print settings/infill/advanced/bridging angle and set it to 180, this will make this model bridge perfectly with minimal support.
Also change the layer heights in overhang areas, and curves as shown in the video.
