Boards drop in by their edges — no screws, no clips, no fasteners. Use them to organize a workbench, kit out a classroom, or finally get your loose Unos out of the parts bin.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat's included\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e42mm standard Gridfinity:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e1-board holder (1x2 footprint)\u003c\/li\u003e\n\u003cli\u003e2-board holder (1x2 footprint)\u003c\/li\u003e\n\u003cli\u003e3-board holder (2x2 footprint)\u003c\/li\u003e\n\u003cli\u003e4-board holder (2x2 footprint)\u003c\/li\u003e\n\u003cli\u003e5-board holder (2x2 footprint)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003e21mm Gridfinity Mini:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e1-board holder\u003c\/li\u003e\n\u003cli\u003e2-board holder\u003c\/li\u003e\n\u003cli\u003e3-board holder\u003c\/li\u003e\n\u003cli\u003e4-board holder\u003c\/li\u003e\n\u003cli\u003e5-board holder\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eEach variant is on its own plate, so you can print only what you need.
