Traditional Mortise and Tenon Splayed Stool | Detachable 3D Printed Solid Wood Style Small Stool

Design Introduction

Recreating the classic structure of traditional Chinese carpentry's splayed four-legged stool, it uses a pure mortise and tenon joint design. It interlocks tightly without screws or glue, restoring the inclined brace mechanical structure used by old carpenters. The four stool legs splay outwards, naturally preventing tipping and providing stable load-bearing. This design combines traditional furniture aesthetics with the modular advantages of 3D printing

The entire structure is broken down into individual parts, with each piece sized to fit most household FDM 3D printers. It's freely scalable (the Bambu Lab A1/P1/X1 full series can print it completely without needing to cut parts). After printing, you can assemble it by hand simply by looking at the diagram, making the assembly threshold very low

Printing Recommended Parameters

• Layer height: 0.2mm
• Wall thickness: 3 walls
• Infill: 15% (sufficient for daily sitting; increase to 30% for higher load-bearing needs)
• Filament: PLA/ABS are both suitable; wood-grain filament provides the closest texture to a solid wood stool

• Support: Only a small amount of support on the inner sloped surfaces of the stool legs, can be optimized for material saving

  Usage Scenarios

• Practical household low stool, shoe-changing stool, balcony small seating stool, capable of stably supporting adults of normal weight
• Chinese miniature furniture ornament, model scene prop, carpentry structure learning aid

• Desktop display, DIY handmade finished product sharing ornament

  Design Highlights

• Splayed diagonal leg mechanical structure, physically self-locking; the more you sit, the tighter the mortise and tenon joint becomes, preventing loosening
• Fully filleted and chamfered corners, no sharp edges, safer for home use
• Modular disassembly, can be laid flat for storage, saving space
