3D PRINTED TRESTLE - DIY

DIY 3D PRINTED TRESTLE – Modular Bracket for 100×50 mm Timber

This modular 3D printed component allows for the construction of sturdy trestles using standard 100 mm x 50 mm timber planks. The joint acts as a structural node between the top beam and the angled legs, ensuring precise alignment, correct angle, and ease of assembly

Key Features:

• Precise alignment of wooden parts
• Correct leg angle for optimal stability
• Simple assembly with standard M8 hardware
• Stable and dismountable structure
• Optimized geometry for FDM printing without supports

Design:

• Internal rib reinforcements to increase rigidity
• Recesses for through-bolts
• Large contact surfaces to distribute load
• Recommended print orientation to leverage layer compression

Recommended Materials and Printing:

• PLA+ / PETG / ASA (depending on use and required strength)
• Infill percentage: 40–60% (gyroid or cubic for better strength)
• No supports required

Timber Specifications:

• Compatible dimensions: 100 mm × 50 mm

BOM (Bill of Materials) – per joint:

• 1× M8 × 100 mm Bolt
• 1× M8 Locknut

For a complete trestle, use multiple joints based on the number of connections between beams and legs

Technical Notes:

• Check timber dimensional tolerance (nominal 100×50 mm may vary by ±2 mm)
• For high-load applications, prefer stronger materials like PETG or ASA
• Print orientation affects strength: position the part so that the layers work under compression
