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 (7)
  • 13 (hubcap-rear-right) does not touch 12 (tyre-rear): a gap of under a millimetre where it is glued; make it meet its host's face in the construct (check --fit)
  • 14 (hubcap-rear-left) does not touch 12 (tyre-rear): a gap of under a millimetre where it is glued; make it meet its host's face in the construct (check --fit)
  • 15 (cowl-engine-upper-receiver) touches only pieces of later sub-assemblies: nothing earlier holds it; give it a face on the piece it belongs to, or move it in the plan's order
  • 16 (cowl-spare-wheel-upper-receiver) touches only pieces of later sub-assemblies: nothing earlier holds it; give it a face on the piece it belongs to, or move it in the plan's order
  • 18 (centre-stand-section-2) does not touch 1 (monocoque): a gap of under a millimetre where it is glued; make it meet its host's face in the construct (check --fit)
  • 23 (hubcap-front-right) does not touch 22 (tyre-front): a gap of under a millimetre where it is glued; make it meet its host's face in the construct (check --fit)
  • 24 (hubcap-front-left) does not touch 22 (tyre-front): a gap of under a millimetre where it is glued; make it meet its host's face in the construct (check --fit)
