Rocket Puzzle – 21 Piece Interlocking Model

This rocket-shaped puzzle is made from 21 unique interlocking pieces that assemble into a compact spacecraft model. Each part slides into place from a different direction, gradually building the full rocket structure piece by piece. Once assembled, the puzzle becomes a solid display piece that looks great on a desk or shelf. Boost MeIf you enjoy my designs, consider boosting this design page so more people can find it!

As the pieces come together, the internal structure locks itself into a stable form, creating a satisfying “final piece” moment when the rocket is complete. It combines the challenge of a brain teaser with the appeal of a small collectible model. This design is also part of a personal challenge I’m doing for the year 2026: designing and releasing a brand new 3D printable model every single day for an entire year. E
