I made changes to a bunch of the pieces, some because they didn’t fit right (not sure if my printer or the part but anything that needed to slide onto the stepper was too small) and some because I used different parts (like 2020 extrusion instead of 2060, M3 screws to attach to the extrusion, and an LM4UU bearing with 4mm rod for the sliding part). I’m not satisfied with the round parts that hold the egg. I made them larger and used neoprene to pad them but that doesn’t stick. It works well enough but definitely room for improvement. The thing I really like about that design is that I can modify these small parts individually making it really easy to iterate.
I plan to refine this in the future. My changes are not in a good state for sharing, but here they are anyway in case it helps (STL and FreeCAD files).
