The two-tone timber gives it a steampunk look that suits a desk or shelf rather than a toy box.\u003c\/p\u003e\u003cp\u003eOnce it's built you crank it, the balls climb, and the whole thing runs on its own for a satisfying few seconds.\u003c\/p\u003e\n\u003ch3\u003eWhat's in the box\u003c\/h3\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\u003ch3\u003eBefore you start\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGlue, batteries and tools are not included\u003c\/strong\u003e — they can't be shipped by air, so buy them locally before you start.\u003c\/li\u003e\n\u003cli\u003eRecommended for ages 14+; the pieces are small.\u003c\/li\u003e\n\u003cli\u003eClear a table you can leave set up for a few evenings.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eFAQ\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eDoes it come with lights?\u003c\/strong\u003e No built-in lighting in this kit. If you want it lit, a short battery LED strip fits neatly behind the finished build.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow big is it when finished?\u003c\/strong\u003e It's designed to sit on a standard bookshelf between your books — roughly the footprint of a hardback, so measure your gap first.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs it beginner friendly?\u003c\/strong\u003e Yes, if you can follow an illustrated manual.

Many builders split it across a weekend.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes it move or play music?\u003c\/strong\u003e It's a static display model.

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.\u003c\/p\u003e","brand":"AnalogMaker","offers":[{"title":"A-Manual Driven","offer_id":52534897967406,"sku":"1005007170126121-A-Manual Driven","price":80.95,"currency_code":"USD","in_stock":true},{"title":"B-Manual Driven","offer_id":52534898000174,"sku":"1005007170126121-B-Manual Driven","price":47.95,"currency_code":"USD","in_stock":true},{"title":"A-Battery Driven","offer_id":52534898032942,"sku":"1005007170126121-A-Battery Driven","price":86.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1005\/5512\/9134\/files\/S72c5456802da46e28e2825ef72f357b9b.webp?v=1788268363","url":"https:\/\/analogmaker.com\/products\/spiral-gear-marble-run-3d-wooden-puzzle","provider":"AnalogMaker","version":"1.0","type":"link"}
