This is a 3D-printable replacement part for the LEGO DUPLO Excavator Arm (Part No. 64771). It is specifically designed for the excavator found in Set 4986 (Diggers), but it fits several other DUPLO construction vehicles.

If your original part has snapped or gone missing, this model allows you to restore the toy to full functionality

Technical Specifications

  • Part ID: 64771 / 4527471

  • Compatibility: LEGO DUPLO Set 4986 and similar construction sets.

  • Design: Recreated to match original dimensions for a perfect snap-fit.

Printing Recommendations To ensure the part is strong enough for play:

  • Material: PETG or ASA (recommended for durability and "flex" without snapping). PLA works also fine.

  • Infill: 25-40%
