Oversized cogs, a spiral funnel and steel balls that keep circling — this is the compact, mechanical end of the marble run range. The two-tone timber gives it a steampunk look that suits a desk or shelf rather than a toy box.
Once it's built you crank it, the balls climb, and the whole thing runs on its own for a satisfying few seconds.
What's in the box
This is a self-assembly 3D wooden puzzle. The box contains laser-cut plywood sheets, the illustrated instructions and the fittings you need — no glue or paint required for the main build.

Glue, batteries and tools are not included — they can't be shipped by air, so buy them locally before you start.

FAQ
Does it come with lights? No built-in lighting in this kit. If you want it lit, a short battery LED strip fits neatly behind the finished build.
How big is it when finished? It's designed to sit on a standard bookshelf between your books — roughly the footprint of a hardback, so measure your gap first.
Is it beginner friendly? Yes, if you can follow an illustrated manual. It's a satisfying step up from the smallest kits: more pieces, more detail, but no special skills or tools needed.
How long does it take? Plan on a few evenings — roughly 6–12 hours depending on how fussy you are with the details. Many builders split it across a weekend.
Does it move or play music? It's a static display model. The finished piece holds its shape on a shelf.
Do I need glue, batteries or tools? Glue and batteries aren't included because they can't be shipped by air. You'll want craft glue (or wood glue) and no batteries for this model. A small craft knife and tweezers help with the finer pieces.
