Since we decided to not use the orbita for now, we needed something to replace connecting Reachy's head to the orbita support. It would just keep the head in a fixed position. I didn't want to make any changes to the orbita support or the head because we will eventually want to use the orbita the future. We should be able to just swap it out without any modifications.

I started off by first importing the head and the orbita support into Fusion 360.

I positioned the head above the orbita support at roughly the same height of orbita. I also made sure that the hole at the bottom of the head was aligned with the orbita support. From inside the orbita support, I projected the edge of the inside bottom onto a sketch. Similarly, I projected the outside edge of the neck of the head onto a sketch.

With the two projected circles, I did a loft to create the basic foundation of my object.

The object was solid though so I hollowed it out using the shell command.

I did this to save on material and printing time. Potentially, wires run though the hole in the bottom of the orbita support through the neck and up into the head.

For the bottom, I added a circle base to the orbita support. I extruded cut out the screw holes based on the holes on the orbita support to make sure that they were perfectly aligned. The screws would be held in by nuts similarly like the camera multiplexer fixture. Again, it has a hole in the center to allow for wires to go through.

I extrude cut access holes so I could get access to the nuts to tighten them or set them in place.

Screw holes for to then head were cut out. I made sure to align them perfectly to the brass inserts in the head.

I realized that I didn't really want to put too much stress on these screws though so I made a little shelf on the inside to support the head.
