A step-by-step guide to building and rebuilding the Space Corps 644PC STEM kit. Learn how to sort pieces, follow the 6-in-1 formations, and keep the fun going.
Quick answer
Start by sorting all 644 pieces by color and shape, then build the first formation directly on a flat surface using the manual. Once complete, display it briefly before disassembling and moving to the next formation. This approach keeps the build organized and the rebuilding fun.
Why sorting first saves time and frustration
With 644 pieces, the Space Corps kit can feel overwhelming if you dump everything into one pile. Sorting by color and shape turns a chaotic search into a quick pick-and-place process. It also helps you spot missing pieces early, before you start building. A muffin tin or a few small bowls make excellent sorting trays.
How to manage the 6-in-1 format without losing pieces
The 6-in-1 design means you will disassemble and rebuild repeatedly. To avoid losing pieces between builds, keep a dedicated container for the kit and return all pieces after each session. Take a photo of each completed formation before disassembling—it serves as a reference for next time and a fun record of what you built.
Step-by-step building process
- Prepare your workspace: Clear a flat, hard surface like a table or floor area. Keep small children and pets away to prevent pieces from getting lost or chewed. A dedicated tray or mat with raised edges keeps pieces from rolling away.
- Sort all 644 pieces: Divide pieces by color and then by shape into bowls or muffin tins. This makes finding pieces faster and helps you confirm everything is present. Count pieces against the manual's parts list if you suspect any are missing.
- Choose your first formation: Pick one of the six formations from the manual. Start with the simplest one if this is your first build, to get familiar with how the pieces connect. Bookmark or photocopy the manual page for the formation you are building.
- Build in stages: Follow the manual step by step, snapping pieces firmly together. Build sub-assemblies first if the manual shows them, then combine. Press pieces until you hear or feel a click to ensure they stay connected.
- Check stability and display: Once complete, gently test the model's stability. Let it stand on a shelf or table for a while before disassembling. Take a photo of the finished model for reference and to celebrate the build.
- Disassemble and store: Carefully pull pieces apart and return them to the sorting trays or storage container. Keep the manual in a safe place for next time. Store the kit in a sealable bag or box to keep all pieces together between builds.
