Not yet built by anyone. This kit was made and checked by software and by AI critics, not test-printed and glued by a person. Print one piece first (each is a named object on its plate, and on its own in pieces/ where the kit was made), check how it fits, and tell us how it went: github.com/rtmandreyev/construct/issues.

For whoever made this kit: what its check found (2)

5 (dial-plate) does not touch 1 (trunk): a gap of under a millimetre where it is glued; make it meet its host's face in the construct (check --fit)
pendulum-rod-upper came out in 2 pieces (10; the rest too small to keep): its parts do not touch; split the merge or bridge it
