This is looking great Alec, one usability suggestion is to highlight the piece you are about to pull off since you can attach parts on parts on parts. I would think it would be the same color as the cylindrical pointer coming out of the mitts.
That is the raw scan, I haven't done any cleanup of the cylinder head. That was 741 photos which took 19 hours to process. I'm getting a 1080ti so hopefully that will cut my processing times by ~30%.
