This is definitely the most complicated design I have worked on so far...
But it is almost done. It took me three iterations for the overall design and another four to get all fittings and especially the cable management right. By now, I am very happy and I will publish the files after a final (?!) test print :))
There are basically two structural parts, the ring and the base, which take nine and four hours to print respectively. The front and back plate are optional and only for aesthetic reasons ;)
Furthermore you will need a small gear and some object holders, which will come in different labeled sizes.
So the total printing time should be well-below 24h.
This design is fully compatible with the raspberry pi shield and ringlight, but there are two additional cables needed (50cm camera cable + 50cm ringlight cable).
I will also add an adapter for the HQ Pi camera and also a new ringlight. I think, I have found a good lens for this distance, but first I will need to do some more testing :)
