The author remixed this model.
Martin's model is fantastically designed, details are great, and well laid out.
I wanted to print this as a hollow resin model, but his single print model was not a solid single piece and messed with the slicer. All the pieces were as if you assembled (all the pins and mounting holes are still there) not boolean'd together to make a solid single piece.
I used Blender to combine all the pieces and removed the internal faces so it can be easily printed hollow to save resin.
I moved Martin's TM maker mark to the bottom where its more symmetrical and less upfront, still giving credit to his design work
