This is a link from the PI camera cable chain but with the snap in connector for 2020 extrusions added. I wanted to be able to have the cable slipped to the printer as sometimes if would catch on the bottom of the bed.
This just twists into the extrusion on the printer.
I printed at 100% infill to give it strength but it would be fine at 20% I think, I just wanted to make sure it wouldn't snap, and it didn't make too much difference in print time anyway.
I also printed a brim but I don't think that matters.
