Who Is This Set For?

Gift for Ages 14+

1,213 pieces with an estimated 4-8 hours fits comfortably into a focused afternoon or weekend session.

Expanding a Educational and Dacta Collection

A solid addition for collectors building out their Educational and Dacta shelf. Introduces parts and builds that complement other sets from the same line.

Build Tips

1

Open bags one numbered sequence at a time — LEGO orders them to match the build stages and keeps loose piece counts manageable.

2

Budget 4-8 hours across multiple sessions rather than one sitting. Fatigue leads to missed connections that are hard to trace later.

3

Keep the instruction booklet after building — it's the most reliable reference for disassembly, cleaning, or reassembly after storage.
